Extract helper functions to simplify complex control flow:
- try_oauth_flow: Extract _start_oauth_session_with_server helper to handle server startup phase, improving readability and testability
- _hetzner_resolve_server_type: Extract _hetzner_log_validation_error and _hetzner_log_type_change helpers to separate error handling logic from main flow
These changes reduce nesting levels and improve function cohesion while maintaining identical behavior.

After an interactive SSH session ends, users are now shown:
- A warning that their server is still running (and may incur charges)
- A link to the cloud provider's dashboard to manage/delete it
- The SSH command to reconnect
This prevents users from unknowingly leaving servers running after
exiting their agent session. Covers all 25 SSH-based cloud providers.

When server destruction fails, users are left with a bare error message and
no indication that they may still be billed for a running server. This adds
dashboard URLs and clear warnings to destroy_server errors across 9 clouds
(Hetzner, UpCloud, Contabo, Netcup, RamNode, Hostinger, HOSTKEY, OVH,
Latitude). Also improves error messages for Koyeb (app creation, service
deployment, deployment timeout, instance ID), GitHub Codespaces (creation
failure, readiness timeout), and E2B (sandbox creation failure).

SSH key registration in 11 cloud providers used unescaped key_name
directly in JSON request bodies. If the hostname (used to generate
key names) contained JSON-special characters like double-quotes, it
could break out of the JSON string and inject arbitrary JSON fields.
Fix: use json_escape for key_name in all providers, matching the
pattern already used by Scaleway.
Also fix GCP create_server which embedded the startup script inline
in --metadata with comma delimiters. Commas in the script could break
metadata parsing or inject additional metadata keys. Fix: use
--metadata-from-file for the startup script.
Affected providers: Hetzner, DigitalOcean, Vultr, BinaryLane,
Hostinger, Contabo, Cherry, HOSTKEY, Civo, Linode, Genesis Cloud, GCP.

- Extract `ensure_jq()` from hetzner and hostkey into shared/common.sh,
eliminating 64 lines of identical duplicated code
- Decompose DigitalOcean `create_server()` by extracting error handling
into `_do_check_create_error()` helper, and using the shared
`extract_api_error_message` instead of inline Python parsing
- Use shared `_extract_json_field` for droplet ID extraction

Hetzner lib: replace all Python JSON parsing with jq. Uses the
/datacenters API as the authoritative source for server type
availability (server_types.available), cross-referenced with
/server_types for specs and pricing. jq is auto-installed if missing.
URLs: update openrouter.ai/lab/spawn → openrouter.ai/labs/spawn
across all READMEs and CLI source.

When HETZNER_SERVER_TYPE and HETZNER_LOCATION are both pre-set (e.g. by
automated scripts), there was no validation that the type is actually
available at that location. ARM types like cax11 are only available in
EU datacenters, causing "unsupported location for server type" errors
when paired with US locations like ash.
Now create_server validates the type against the Hetzner /datacenters
API (server_types.available) before attempting creation. If incompatible,
it auto-selects the cheapest compatible alternative (same CPU family,
>= specs) and warns the user.
Uses jq for JSON parsing (auto-installed if missing) and the Hetzner
/datacenters + /server_types APIs for authoritative availability data.

Replace 10 inline `python3 -c "import json,sys; d=json.loads(...)..."` one-liners
across vultr, hetzner, digitalocean, and contabo with calls to a new shared
`extract_api_error_message` helper in shared/common.sh. The helper tries common
JSON error field patterns (message, error, error.message, error.error_message,
reason) and falls back to a caller-specified default.
This pattern appears 35+ times across cloud libs; this PR converts the first 4
clouds as a proof of concept. Remaining clouds can adopt incrementally.
Net reduction: 10 lines per converted cloud (~3 lines saved per call site).

Add ssh_run_server, ssh_upload_file, ssh_interactive_session, and
ssh_verify_connectivity to shared/common.sh. These four functions
were copy-pasted identically across 21 cloud provider lib files,
differing only in SSH username (root vs ubuntu).
Providers now set SSH_USER and delegate to the shared helpers via
one-line wrappers, reducing each provider's lib by ~20 lines.

* ux: Improve error messages and user guidance across CLI and shell scripts
Enhanced error messages to be more actionable and user-friendly:
CLI improvements (commands.ts):
- Made validateNonEmptyString clearer: "is required but was not provided"
- Reordered troubleshooting steps to check matrix first (most common issue)
- Simplified 404 error message: "doesn't exist yet" vs "may not be implemented"
- Changed "Troubleshooting steps" to just "Troubleshooting" (less formal)
Shared library improvements (shared/common.sh):
- OAuth cancellation now explains why API key is needed and where to get it
- safe_read non-TTY error explains what non-interactive mode is with example
- get_resource_name error shows exact env var syntax needed
- Agent verification failures now list specific possible causes
- All improvements add context and next steps rather than just stating the problem
Hetzner library improvements (hetzner/lib/common.sh):
- Replaced technical "Remediation" with friendly "How to fix"
- Changed log_warn to log_error for error conditions (consistent severity)
- Added spacing for better readability of multi-line errors
- Made server creation errors more specific about account issues
All changes focus on helping users understand WHAT went wrong and HOW to fix it.

- hetzner/lib/common.sh:31 - HCLOUD_TOKEN set by caller
- digitalocean/lib/common.sh:36 - DO_API_TOKEN set by caller
- Silences false positive warnings for intentionally external variables
- These tokens are exported by ensure_*_token functions before use
Fixed 2 critical syntax errors in API error handling:
- Hetzner line 160-161: Malformed error_msg assignment
- DigitalOcean line 172-173: Broken error_msg assignment
These were introduced during Round 15 refactoring and would crash
whenever users encountered API errors during server creation.

Add SC2086 disable comments to interactive_session() functions in

Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Eliminates duplicate SSH key registration logic across 5 cloud providers
(Hetzner, DigitalOcean, Vultr, Linode, Lambda) by introducing a generic
callback-based pattern in shared/common.sh.
Before: Each provider had ~45 lines of nearly identical code for:
- Generating SSH keys if missing
- Getting fingerprints
- Checking if key exists with provider
- Registering key if not exists
- Error handling
After: Providers implement 2 simple callbacks:
- check_callback: provider-specific API call to check if key exists
- register_callback: provider-specific API call to register key
The shared function handles:
- Key generation (via generate_ssh_key_if_missing)
- Fingerprint extraction (via get_ssh_fingerprint)
- Flow control and logging
- Callback orchestration
Changes:
- shared/common.sh: Added ensure_ssh_key_with_provider() function
- hetzner/lib/common.sh: Refactored to use callbacks
- digitalocean/lib/common.sh: Refactored to use callbacks
- vultr/lib/common.sh: Refactored to use callbacks
- linode/lib/common.sh: Refactored to use callbacks
- lambda/lib/common.sh: Refactored to use callbacks
Benefits:
- DRY: Eliminates ~220 lines of duplicate code
- Maintainability: Bug fixes in registration flow benefit all providers
- Consistency: All providers use identical registration logic
- Extensibility: New providers can reuse this pattern

SSH_OPTS contains multiple flags that must be word-split, so unquoted
usage is intentional. Added shellcheck directives to suppress false
positive warnings across all cloud provider common.sh files.
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
Added shellcheck directive comments before first SSH_OPTS usage in:
- aws-lightsail/lib/common.sh
- gcp/lib/common.sh
- lambda/lib/common.sh
- vultr/lib/common.sh
- linode/lib/common.sh
- hetzner/lib/common.sh
- digitalocean/lib/common.sh
SSH_OPTS is defined in shared/common.sh but shellcheck can't detect
cross-file variable definitions, so we suppress the warning with
an explanatory comment.

The autonomous refactoring added `set -euo pipefail` but the scripts
check optional env vars with `[[ -n "$VAR" ]]` which is a fatal error
under nounset when the var isn't set (e.g. SPRITE_NAME, OPENROUTER_API_KEY).
Fix: downgrade to `set -eo pipefail` across all 42 affected files.

When scripts run via `bash <(curl ...)`, BASH_SOURCE resolves to
/dev/fd/N, making the relative path `../../shared/common.sh` fail.
Fix: add remote fallback — try local file first, fall back to

digitalocean, vultr, linode).

Three issues broke the OAuth callback server on macOS:
1. echo -e doesn't work in bash 3.x — \r\n appears as literal text
in the HTTP response, browser gets malformed headers.
Fix: pre-write response with printf to a file before the subshell.
2. local variables inside ( ... ) & subshell — undefined behavior in
bash 3.x since subshells aren't function scope.
Fix: use plain variables in subshells.
3. ((elapsed++)) when elapsed=0 evaluates to falsy — set -e kills
the script on the first iteration of the timeout loop.
Fix: use elapsed=$((elapsed + 1)) instead.
Also simplified nc_listen detection to only check for BusyBox
(the -p flag check could misfire on macOS nc).
Applied to all 10 lib/common.sh files.
