Repair AB props defaults and reader extraction

[purpshell]

Make AB props extraction fail closed on unsupported defaults and preserve literal booleans, strings, nulls and numeric values. Extract reader-property names strictly from shipped declarations, reconcile declaration counts, and retain removed-property evidence.

Validation: Rust extractor tests pass; full extraction from WhatsApp Web 1049861608 at source revision 85b7532 produces 6002 facts and regenerates Polymorfa's Go/TypeScript catalogs byte-identically. Reader inventory includes 686 modules.

API/SDK/CLI: this extractor changes no public runtime contract. Docs: coordinated backend catalog provenance and plan. Feature releases: no package publication, rollout or customer availability change. Admin: existing generated catalog controls remain in the backend.

Summary by CodeRabbit

• Bug Fixes
  • A/B property extraction now reports errors for unreadable modules, malformed or unsupported defaults, and mismatches between declared and extracted entries instead of returning partial results or coercing values.
  • Defaults support JSON-compatible scalar values, including strings, numbers, booleans, and null.
  • Property and reader names now match regardless of letter case, while reader names retain their original casing.

📝 Walkthrough

Walkthrough

A/B property extraction now parses supported scalar defaults from module source and propagates module-read and parsing errors. It also accepts mixed-case property and reader names, validates extracted-entry counts, and includes tests for supported and rejected defaults.
