Lex Christopherson 9099d48495 perf(intel): simplify SessionStart hook + gitignore intel/
- SessionStart now reads pre-generated summary.md directly
- No more JSON parsing of potentially large index.json
- Added guidance: .planning/intel/ should always be gitignored
  (changes constantly, can be regenerated with /gsd:analyze-codebase)
