Bring the planning docs up to date with reality from the changelog and
recent merges:
- Mark the .ics engine (export + import) shipped in v2.7.0 and local-
calendar backup done; clear the stale "in progress" tags.
- Note snooze/dismiss merged into release/v2.8.0 alongside Codeberg
crash reports.
- Record drag-and-drop rescheduling as consciously rejected.
- Promote attendee editing out of the gated bucket into Tier 5 #12
(read side already shipped in v0.6; only the write side is missing),
with the sync-adapter invitation caveat to resolve first.
- Refresh STATE.md (was stuck at v2.4) through v2.7.5 and the 2.8.0
integration branch.
