[instructions] Sync instruction files — fix cli-proxy and reduce safe-outputs.md

[github-actions]

Instructions Update — Sync after recent changes

This PR updates instruction files in .github/aw/ based on audit of current code vs. documentation accuracy and file size limits.

Files Changed

• syntax.md: Fix cli-proxy feature flag description — previous wording conflated cli-proxy and integrity-reactions by saying "and reaction-based integrity decisions" and including integrity-reactions-specific content ("Compiler automatically enables cli-proxy") in the cli-proxy entry. Corrected to describe cli-proxy's actual purpose (secure read-only gh CLI access without exposing GITHUB_TOKEN) and clarify it is a prerequisite for integrity-reactions.

• safe-outputs.md: Reduce from 1058 lines to 994 lines (below hard limit of 1000) by:

  • Removing ~18 redundant "When using safe-outputs.X, the main job does not need write permissions" sentences (this principle is already stated in the file's introduction)
  • Condensing the "Output Processing and Issue Creation" section (35 lines) to a compact "Output Variables" table (11 lines) — the rest was duplicated with earlier content
  • Streamlining create-project: and update-project: PAT token requirements that were duplicated across 3 sections

Documentation Commits Reviewed

• 178adc3 feat: split github-agentic-workflows.md into focused sub-files and update instructions-janitor

All changeset files were reviewed. All documented features are consistent with current code.
