fix(cache): add analysis_profile to cache payload for min-loc/min-stm…

[orenlab]

Fixes #9

• Cache schema bumped from v1.2 to v1.3 (fail-open behavior preserved).
• Added signed analysis_profile (ap: {min_loc, min_stmt}) to cache payload.
• Cache compatibility now requires analysis_profile to match active CLI thresholds.
• On profile mismatch: warning + cache ignored; new CacheStatus=analysis_profile_mismatch.
• CLI now passes effective thresholds into Cache(...).
• Added contract and CLI in-process regression coverage for:
  • ap roundtrip in cache payload,
  • profile mismatch bypassing cache,
  • profile match preserving cache-hit behavior.
• Baseline contract unchanged (schema v1.0, fingerprint v1).

Sanity checks:

• Legacy cache v1.2 now yields version_mismatch warning, rc=0, analysis continues (cache_hits=0).
• Mismatch warning includes found vs expected profile values.
• ap remains deterministic (canonical JSON with sorted keys) and strictly validated ({min_loc,min_stmt} with int values).
