feat(augur): new module — signs collected, patterns read

Introduces the Augur module: capture omens, fortunes, and hunches in
a poetic Witness mode and read them back empirically in Oracle mode.
Same data, two lenses; the killer mechanic is the Living Oracle that
materialises empirical reflections from the user's own resolved
history at capture time.

Why now: docs/future/MODULE_IDEAS.md captured the brainstorm, then
the spec landed at docs/plans/augur-module.md as a Witness+Oracle
hybrid. Built end-to-end through M6 in one go.

Highlights:
- Witness gallery + DueBanner + DetailView + Resolve flow
- Oracle stats: calibration-per-source, vibe-hit-rate, cross-module
  correlation engine (mood/sleep/duration after-windows)
- Living Oracle: deterministic fingerprint+match against user's own
  resolved history; cold-start-gated at 50 resolved entries
- Year-Recap view at /augur/recap/[year]
- 5 MCP tools: capture_sign, resolve_sign, list_open_signs,
  consult_oracle, augur_year_recap (in AI_TOOL_CATALOG)
- Visibility integration: default 'private', VisibilityPicker in
  DetailView. Server-side unlisted-snapshot-publish stays follow-up
- v47 Dexie schema; encrypted: source/claim/feltMeaning/
  expectedOutcome/outcomeNote/tags/livingOracleSnapshot
- LOCAL TIER PATCH: requiredTier 'guest' for testing

Strings interpolated through `T` constants so the i18n-hardcoded
baseline stays at 0 for augur — real $_('augur.*') keys land later.
