Support Apple Contacts record schema

[pheidon]

Summary

• add a Contacts reader path for modern AddressBook-v22.abcddb schemas using ZABCDRECORD
• preserve the existing synthetic contacts table support for fixtures and tests
• map names, organization, optional notes, emails, and phones from schema-detected Apple Contacts tables
• add fixture-backed coverage for search, note redaction, and email/phone aggregation

Validation

• git diff --check
• GitHub PR Fast CI / CI Gate: passed on b7f870c
• Hermes/macOS: swift test --disable-sandbox passed, 62 tests
• Hermes/macOS: swift build -c release passed

Privacy

• Hermes schema discovery used PRAGMA/table metadata only; no contact rows or values were queried
• Hermes validation did not run live contacts list, so no real names, emails, phones, or notes were printed

Reviewed this pass; no blocking issues found.

The Apple Contacts schema fallback and record mapping look coherent, including the field extraction, notes handling/redaction behavior, and fixture coverage for the new contacts shape. I do not see a code defect or test gap that should block this PR.

Merge call: ready to merge from my review.

Reviewed the contact schema change. I did not find blocking issues. The schema fallback, Contacts field mapping, note redaction behavior, and fixture coverage look coherent to me. This is ready to merge from my pass.
