fix(git): handle Git redirects and improve URL parsing for tangled.sh and other Git hosts

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
