feat(detail): full event read — surface every readable field (v0.6.0)

Round out the read-only model so the detail view shows everything
CalendarContract actually stores, ahead of write support.

Data layer:
- New domain types: Reminder, EventStatus, Availability, AccessLevel,
  AttendeeRelationship, AttendeeType; EventDetail gains reminders, status,
  availability, accessLevel, eventTimezone, selfStatus and Attendee gains
  relationship + type (all defaulted so existing callers compile)
- EventDetailProjection reads STATUS / AVAILABILITY / ACCESS_LEVEL /
  EVENT_TIMEZONE / SELF_ATTENDEE_STATUS; AttendeeProjection reads
  RELATIONSHIP + TYPE; new ReminderProjection queries CalendarContract.Reminders
- Mappers translate each provider integer code, guarding STATUS's null-vs-0
  ambiguity (0 == TENTATIVE) so an absent status reads as Confirmed
- Mapper unit tests cover every new column's codes

Detail UI:
- Status / availability / access chips under the title; cancelled also strikes
  the title through
- Reminders card with humanised lead times (plurals, DE + EN)
- Foreign-timezone card, shown only for timed events in a non-device zone
- Attendee role badges + the user's own "Your response: …" line
- http(s) URLs in the description are now tappable

URL field cut: CalendarContract exposes no Events.URL column (only the
CUSTOM_APP_URI app deep-link), so URLs are surfaced by linkifying the
description instead. Recorded in ROADMAP/CHANGELOG.

Version bumped to 0.6.0 / 6.

+### Added
+- Full event read (v0.6): the detail screen now surfaces every readable
+  `CalendarContract` field that V1 had been dropping —
+  - **Reminders** — each configured lead time, humanised ("10 minutes before",
+    "1 day before", "At time of event"), read from `CalendarContract.Reminders`
+  - **Status** — Tentative / Cancelled chip under the title; a cancelled event
+    also strikes through its title (Confirmed shows no chip)
+  - **Availability** — a Free / Busy chip (`Events.AVAILABILITY`, the iCal
+    TRANSP field)
+  - **Access level** — a Private / Confidential chip when the event isn't public
+  - **Attendee role** — organizer / optional / resource badge under each
+    attendee, plus the device user's own response ("Your response: …") from
+    `Events.SELF_ATTENDEE_STATUS`
+  - **Time zone** — shown only for timed events pinned to a zone other than the
+    device's, so cross-zone events read unambiguously
+  - **Linked URLs** — http(s) links in the description are now tappable
+- Domain model rounded out with `Reminder`, `EventStatus`, `Availability`,
+  `AccessLevel`, `AttendeeRelationship`, `AttendeeType`, and the attendee/self
+  status fields; mappers + unit tests cover every new column's integer codes
+
+### Changed
+- `versionName`/`versionCode` bumped to 0.6.0 / 6
+
+### Notes
+- A dedicated event **URL** field was dropped from scope: `CalendarContract`
+  has no `Events.URL` column (only `CUSTOM_APP_URI`, an app deep-link), so URLs
+  are surfaced by linkifying the description instead
