Codeberg #15, foundation for the contact special-dates calendars. Declares the
optional, feature-gated READ_CONTACTS permission (never requested at startup)
and adds the offline, read-only contacts reader.
- AndroidManifest: READ_CONTACTS with a comment documenting the opt-in/offline
one-way-mirror contract.
- domain/contacts: SpecialDateType + ContactSpecialDate model and a pure
parseContactEventDate covering full (yyyy-MM-dd), year-less (--MM-dd) and
compact (yyyyMMdd) shapes, with Feb-29 handling via a leap anchor.
- data/contacts: ContactSpecialDatesDataSource querying ContactsContract.Data
Event rows, split by TYPE, deduped per (contact, type); returns empty without
the permission so sync can degrade to a stalled state. Hilt-bound.
- Unit tests for the date parser (full/year-less/compact/Feb-29/malformed).
