Fixes deployment failures when Git repositories redirect (e.g., tangled.sh → tangled.org)
and improves security by adding proper shell escaping for repository URLs.
**Root Cause:**
Git redirect warnings can appear on the same line as ls-remote output with no newline:
`warning: redirecting to https://tangled.org/...196d3df... refs/heads/master`
The previous parsing logic split by newlines and extracted text before tabs, which
included the entire warning message instead of just the 40-character commit SHA.
**Changes:**
1. **Fixed commit SHA extraction** (ApplicationDeploymentJob.php):
- Changed from line-based parsing to regex pattern matching
- Uses `/([0-9a-f]{40})\s*\t/` to find valid 40-char hex commit SHA before tab
- Handles warnings on same line, separate lines, multiple warnings, and whitespace
- Added comprehensive Ray debug logs for troubleshooting
2. **Added security fix** (Application.php):
- Added `escapeshellarg()` for repository URLs in 'other' deployment type
- Prevents shell injection and fixes parsing issues with special characters like `@`
- Added Ray debug logs for deployment type tracking
3. **Comprehensive test coverage** (GitLsRemoteParsingTest.php):
- Tests normal output without warnings
- Tests redirect warning on separate line
- Tests redirect warning on same line (actual tangled.sh format)
- Tests multiple warning lines
- Tests extra whitespace handling
**Resolves:**
- Linear issue COOLGH-53: Valid git URLs are rejected as being invalid
- GitHub issue #6568: tangled.sh deployments failing
- Handles Git redirects universally for all Git hosting services
