Make bare /race-hub resolve to a completed session and never open empty
post-session analysis for a future race.
- Backend: add `default_analysis_session` to the Weekend context. It never
resolves to a future session (picks the richest completed session, ties
toward the later one; 0 when everything is upcoming). Existing
`default_session_key` and deep links are unchanged.
- Frontend default resolution prefers the most recently completed weekend
(`pickAnalysisFocusMeeting`) and consumes `default_analysis_session`, falling
back to the switcher when only upcoming sessions exist.
- New `sessionState` lib maps timing + coverage to user language
(upcoming/live/preparing/partial/ready/cancelled); the session rail, active
sub-bar, and WeekendSwitcher now label states instead of raw x/11 counts.
- Future sessions render a purpose-built PreSessionView (expected availability +
countdown) instead of empty Winner/Podium/Pole/Strategy/Compare cards.
- Analysis navigation regrouped into Story / Analysis / Data & Context; every
existing tab is preserved. Diagnostics (renamed from Data Status) is now a
secondary action and the raw dataset strip is hidden behind an explicit
toggle, so operational coverage no longer precedes fan content.
- Loading/error states offer Retry and a path back to Weekend.
Tests: Go query tests for future-exclusion; Vitest for default selection,
future pre-session, partial state, error/retry, grouped nav, and sessionState;
hermetic Playwright for bare/completed/future/return-to-Weekend; new
race-hub-future visual snapshots. Seed adds a far-future session inside the
Monaco meeting (kept in-meeting so Command Center focus is unaffected).
Note: `default_analysis_session` is an additive field on the existing
`/weekend` contract (no new endpoint), per the spec's "context contract" scope.

Add deterministic server-side chapter detection for starts, flag periods, pit phases, decisive top-five swings, and finishes, then expose chapters on the race-hub payload.
Spike result: race-hub already loads race control, positions, and laps in one read model. The requested Detect signature does not include pit stops, so pit phases use IsPitOutLap clusters as the local deterministic pit-stop proxy.
