Add grep flags reference table to SKILL.md for quick lookup

Introduce a concise reference line documenting all common grep flags (--path, --glob, --output-mode, --context-lines, --from-line/--to-line, --reverse, --case-sensitive) and command-specific flags (--branch/--no-clone for code grep, --log-id for pipeline grep) to reduce flag discovery friction. Place reference immediately after command table for easy scanning.

+All grep commands (code, pipeline logs, artifacts) support: `--path`, `--glob`, `--output-mode` (content/files_with_matches/count), `--context-lines`, `--from-line`/`--to-line`, `--reverse`, `--case-sensitive`. Code grep adds: `--branch`, `--no-clone`. Pipeline grep adds: `--log-id`.

 Rules that save retries:
 
 - **GitHub**: repo arg is bare `<repo>`, not `org/repo`. Search output may look like `org/repo:path` but commands still take `<repo>`.
