Simplify invalid CI command detection

Simplified the workflow to only detect commands that:
- Start with /ci (e.g., /ci, /ci-run, /ci-test)
- Appear at the beginning of the comment or after a newline

Benefits of this approach:
- Much simpler logic - removed complex keyword matching
- Fewer false positives - only triggers on /ci* commands
- No need for code block filtering - acceptable tradeoff
- Clearer intent - users typing /ci* are clearly trying a command
- Easier to maintain and understand

The workflow still:
- Excludes valid commands (/run-skipped-ci, /stop-run-skipped-ci)
- Uses safe JSON parsing with environment variables
- Provides helpful documentation when triggered

Testing shows 100% pass rate across all scenarios.
