Agent Code Guard 0.3.0

Added

• Opt-in guards.loc.ratchetAt: "review" support freezes source-controlled LOC allowances beginning above the effective review threshold, while omitted or explicit "fail" preserves the existing failure-only lifecycle and output.

Fixed

• Known per-file syntax and provider failures now produce blocking structured incomplete results while preserving independent LOC, Markdown, and unaffected syntax evidence; completed output remains schema- and byte-compatible.
• Valid C# that uses async as an expression identifier or named-argument name now receives a narrow, coordinate-preserving parser compatibility retry while unknown, ambiguous, and malformed syntax still fails closed.
