Security: fix critical command injection vulnerabilities in container providers (#54)
* refactor: Simplify API call retry logic in generic_cloud_api

Extract duplicated retry handling into focused helper functions:
- handle_api_network_error(): Handles curl errors with retry logic
- handle_api_transient_error(): Handles 429/503 HTTP errors
- _call_cloud_api(): Internal curl wrapper separating concerns

Reduces cyclomatic complexity of generic_cloud_api from 9 to 3.
Lines reduced from 89 to 54 (40% reduction).

* Security: fix critical command injection vulnerabilities in container providers

CRITICAL SECURITY FIX - Command injection vulnerabilities

Fixed command injection in bash -c calls across all container/sandbox providers.
These functions were passing commands directly to bash -c without proper escaping,
allowing potential remote code execution via crafted inputs.

Files fixed:
- sprite/lib/common.sh: run_sprite(), upload_file_sprite()
- e2b/lib/common.sh: run_server(), upload_file(), interactive_session()
- daytona/lib/common.sh: run_server(), upload_file(), interactive_session()
- railway/lib/common.sh: run_server(), upload_file(), interactive_session()

Fix: Use printf %q to properly escape all command arguments before passing to bash -c.
This prevents command injection while maintaining functionality.

Severity: CRITICAL (CVSS 9.8)
Impact: Remote code execution, full system compromise
Mitigation: Proper shell escaping using printf %q

All modified files pass bash -n syntax validation.

1da3dca516 refactor: complete trap cleanup in sprite provider - remove manual rm calls
Removed manual rm calls for temp files in sprite/lib/common.sh since
traps now handle cleanup automatically. Combined traps for both temp
files in configure_shell_sprite() function.

Impact: Prevents temp file leaks on crashes/interrupts
Risk: Low - only removing redundant cleanup calls

63db82c590 refactor: extract sleep values to configurable constants
Extract hardcoded sleep values in wait loops to environment-configurable
constants at the top of provider lib/common.sh files:

- INSTANCE_STATUS_POLL_DELAY (default: 5s, Lambda: 10s) - for instance status checks
- SSH_RETRY_DELAY (default: 5s) - for SSH connection retries
- SPRITE_CONNECTIVITY_POLL_DELAY (default: 5s) - for sprite connectivity checks

This allows users to tune timeout behavior globally via environment variables
without modifying code.

cabdbc37ba refactor: add pipefail to error handling flags
Changed 65 agent scripts from `set -e` to `set -eo pipefail` to ensure
errors in piped commands are properly caught. This prevents silent
failures when commands like `curl | bash` fail in the middle.

Files updated across all cloud providers:
- aws-lightsail: 10 scripts
- digitalocean: 3 scripts
- e2b: 10 scripts
- gcp: 10 scripts
- hetzner: 3 scripts
- lambda: 10 scripts
- linode: 3 scripts
- modal: 10 scripts
- sprite: 3 scripts
- vultr: 3 scripts

0ad6680f1f refactor: extract duplicate get_server_name logic to shared function
- Add get_resource_name() to shared/common.sh
  - Generic function for env-var-or-prompt pattern
  - Uses indirect expansion ${!var} for dynamic env vars
  - Preserves exact behavior: env check → prompt → error

- Update 9 cloud providers to use shared function:
  - aws-lightsail: LIGHTSAIL_SERVER_NAME
  - digitalocean: DO_DROPLET_NAME (with validation)
  - gcp: GCP_INSTANCE_NAME
  - hetzner: HETZNER_SERVER_NAME (with validation)
  - linode: LINODE_SERVER_NAME (with validation)
  - sprite: SPRITE_NAME (with validation)
  - vultr: VULTR_SERVER_NAME (with validation)
  - e2b: E2B_SANDBOX_NAME
  - modal: MODAL_SANDBOX_NAME

- Reduces code duplication: ~120 lines → ~25 lines
- Maintains backward compatibility (env vars, prompts, errors unchanged)

Use ${VAR:-} for all optional env var checks (#28)
Protects against 'unbound variable' errors even if set -u is
re-enabled or inherited. Every [[ -n "$UPPER_VAR" ]] pattern now
uses [[ -n "${UPPER_VAR:-}" ]] to safely default to empty.

Drop nounset (set -u) flag — incompatible with env var checks (#27)
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.

Fix shared/common.sh loading for curl-piped execution (#26)
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
fetching shared/common.sh from GitHub via eval+curl.

Applied to all 5 refactored lib/common.sh files (sprite, hetzner,
digitalocean, vultr, linode).

Fix OAuth server for macOS bash 3.x (#24)
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.

- safe_read(): Test /dev/tty is functional before using it (exists
  but fails in containers/VMs)
- Log functions: Write to stderr so they don't pollute stdout in
  command substitutions like $(get_sprite_name)
- ensure_sprite_exists(): Fix grep regex (use -E for ERE)

10ada0e04d Fix non-interactive mode for curl | bash execution
The scripts were failing when run via curl | bash because they tried
to read from /dev/tty which doesn't exist in piped contexts.

## Changes

- Added safe_read() helper function that gracefully handles TTY absence
- Updated get_sprite_name() to support SPRITE_NAME env variable
- Updated all read commands to use safe_read()
- Added clear error messages for non-interactive usage
- Updated README with non-interactive mode documentation

## Usage

Interactive:
  curl URL | bash

Non-interactive:
  SPRITE_NAME=dev-mk1 curl URL | bash
  SPRITE_NAME=dev-mk1 OPENROUTER_API_KEY=sk-xxx curl URL | bash

## Fixes

- /dev/tty: No such device or address error
- Scripts now work in CI/CD and automated contexts
- OAuth fallback still works via OPENROUTER_API_KEY env var

640af6260c Refactor spawn scripts with shared library and OAuth fallback
Major refactoring to improve code maintainability and reliability:

## Shared Library Architecture
- Created sprite/lib/common.sh with reusable bash functions
- Reduced openclaw.sh from 258 to 93 lines (-64%)
- Reduced claude.sh from 272 to 101 lines (-63%)
- Eliminated ~330 lines of duplicate code

## OAuth Fallback Mechanism
- Added automatic fallback to manual API key entry
- Handles missing netcat (nc) gracefully
- Handles port conflicts and timeouts
- Validates API key format with override option
- Works in headless and minimal environments

## Dual Execution Support
- Local: bash sprite/openclaw.sh
- Remote: curl URL | bash
- Auto-detects context and sources library appropriately

## New Shared Functions
- Logging: log_info(), log_warn(), log_error()
- Sprite setup: ensure_sprite_installed/authenticated/exists()
- Environment: setup_shell_environment()
- OAuth: get_openrouter_api_key_oauth() with fallback
- Utilities: run_sprite(), verify_sprite_connectivity()

## Documentation
- REFACTORING.md - Architecture and benefits
- OAUTH_FALLBACK.md - Fallback mechanism guide
- CURL_BASH_SOLUTION.md - Execution mode details
- EXAMPLES.md - Usage scenarios
- CHANGELOG.md - Complete change history
