* feat: add VM reconnect functionality to spawn list (#1144)
Implements ability to reconnect to previously spawned VMs instead of
always creating new instances. Changes include:
- Add VMConnection interface to track IP, user, and server metadata
- Add save_vm_connection() bash function for scripts to persist connection info
- Modify spawn list to show connection status and offer reconnect option
- Support both SSH (cloud providers) and sprite console reconnection
- Update digitalocean/claude.sh and sprite/claude.sh as reference implementations
Fixes#1144

* improve: add helpful error message when VM reconnect fails
Show user-friendly message suggesting to spawn a new VM if
reconnection fails, rather than just showing raw SSH error.

echo "$response" | grep -q can cause "write error: Broken pipe" when
grep -q exits early and echo gets SIGPIPE. This is non-deterministic
and depends on response size and timing, which is why it only fails
intermittently in CI. Using [[ == *pattern* ]] avoids pipes entirely.

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.

Unquoted `<< EOF` heredocs in nanoclaw .env file creation cause shell
expansion of the API key value. If an API key contains `$`, backticks,
or `\`, the value is silently corrupted or could trigger command
execution. Replace with `printf '%s'` which safely writes the value
without interpretation.
Also fix unquoted variable expansion in upload_config_file's mv command
and the github-codespaces/openclaw.sh config heredoc.
Fixes 34 scripts across all cloud providers.

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.

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).

~1500 progress messages across 481 files were using log_warn (yellow)
for normal status updates like "Installing...", "Setting up...",
"Creating server...", etc. This made users think something was wrong
when everything was proceeding normally.
Changes:
- Replace log_warn with log_step for all progress/status messages
- Keep log_warn only for actual warnings (errors, remediation hints)
- Remove emoji from 3 sprite completion messages

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.

The upstream OpenCode installer pipes `curl -# -L | tar xz` which fails
in container exec environments (Sprite, E2B, Modal, Daytona) where the
binary stream gets corrupted through the exec layer, producing
"gzip: stdin: not in gzip format" errors.
Added opencode_install_cmd() to shared/common.sh that downloads the
binary to a file first, then extracts it. Updated all 17 opencode.sh
scripts to use this robust method instead of the upstream installer.
The previous fix (#44) only addressed Sprite with a hardcoded
linux-x86_64 architecture. This fix detects OS/arch dynamically and
applies to all cloud providers.

- fly/goose.sh: Block's Goose agent with OpenRouter provider
- fly/codex.sh: OpenAI Codex CLI with OpenRouter base URL override

Fixed SC2086 warnings by adding quotes around ${INSTANCE_STATUS_POLL_DELAY}
in 4 provider libraries. This prevents potential word splitting bugs if
the variable contains unexpected whitespace.
Files updated:
- linode/lib/common.sh:231
- vultr/lib/common.sh:226
- aws-lightsail/lib/common.sh:133
- digitalocean/lib/common.sh:211
Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
- hetzner/lib/common.sh:31 - HCLOUD_TOKEN set by caller
- digitalocean/lib/common.sh:36 - DO_API_TOKEN set by caller
- Silences false positive warnings for intentionally external variables
- These tokens are exported by ensure_*_token functions before use
- 5 nanoclaw scripts only create DOTENV_TEMP but trap referenced both
- Causes trap to fail silently when trying to rm undefined variable
- Fix: Change trap from both temps to just DOTENV_TEMP
- Affected: digitalocean, hetzner, linode, sprite, vultr
Root cause: Automated trap addition in Round 19 incorrectly detected
these files as using both temp variables (DOTENV_TEMP contains substring
ENV_TEMP which caused false positive in grep check)
- Add trap 'rm -f "${ENV_TEMP}"' EXIT after mktemp creation
- Scripts with DOTENV_TEMP get combined trap for both files
- Remove manual rm calls that are now redundant
- Prevents temp file leaks on early script exit (errors, signals)
- Affects 67 agent scripts across all providers
Impact: Prevents /tmp pollution in production deployments
Score: 90 (Impact: 9, Confidence: 10, Risk: 1)
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 explicit timeout parameter (60 seconds) to all wait_for_cloud_init calls
across linode, vultr, digitalocean, hetzner, gcp, and aws-lightsail providers.
This makes timeout configuration more explicit and easier to tune per-provider
or per-agent in the future. The value of 60 matches the default in the
wait_for_cloud_init function implementations.
Modified 60 agent scripts (10 agents × 6 providers).

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
