v2.7 Branch 2 (core, no UI yet). The read side of the .ics engine:
- domain/ics: IcsParser (inverse of IcsWriter) — unfold/unescape/param
parsing, VALUE=DATE / UTC-Z / TZID date handling resolved against the OS
tz db, VEVENT walk → ParsedIcsEvent + typed warnings. Liberal-in/
strict-out: a malformed VEVENT is skipped, RECURRENCE-ID overrides /
attendees / unresolved TZIDs are reported, not silently dropped.
- Promoted parseRfc2445DurationMillis into domain/ics (shared by writer-
side mapper and parser); IcsDuration + test.
- Datasource existingUids()/insertImportedEvent(); repository
importEvents() with UID dedup (skip known UIDs → idempotent restore) →
IcsImportSummary. IcsImporter reads a Uri's text.
- ParsedIcsEvent.toEventForm() for the single-event "open into the create
form" path.
Parser round-trips against IcsWriter; dedup + form-adapter unit-tested.
Intent filter, routing and import UI land in the next commit.
