Phase 4: task-to-goal integration (Vision side)

Build the boundary the ImpactFlow core time-tracker plugs into. A task maps to
a foundation — one of the six stable profile elements (love, strength, mission,
vocation, short_term, long_term) — so the tracker can ask "which goal does this
build toward?" and post the answer back to Vision.

- Models + migration 006: task_mapping (one row per logged time entry).
- app/services/foundations.py: the six foundations + a pure, testable
  work-pattern aggregator (rollup) and a plain-language summary.
- app/routers/integration.py (user-scoped; tracker calls as the user or via
  X-API-Key): GET /foundations, POST/GET /task-mappings,
  GET /work-patterns?days=N (per-foundation minutes/share/neglected).
- Reminder engine now pulls from real work patterns: CheckinCoach takes an
  optional work-pattern summary (last 14 days) and reflects where time has gone
  against the person's own words — an observation, never a verdict.
- Frontend: dashboard.html (time per foundation + neglected); linked from
  profile.html.

Documented the core-tracker integration contract in the README. Phase 4
completes the Vision module's roadmap on the Discovery side; the core tracker
integrates by calling these endpoints.

Tests: 86 passing (added pure-aggregator, integration-endpoint, and
work-pattern-into-check-in tests; run in-container).

+"""Phase 4 integration routes: the boundary the ImpactFlow core time-tracker
+plugs into.
+
+When a user logs time in the core tracker, the tracker asks "which goal does
+this build toward?" — fetching the options from ``GET /foundations`` — and
+posts the answer to ``POST /task-mappings``. ``GET /work-patterns`` rolls those
+up to feed the coaching reminder engine and the goal dashboard.
+
+All routes are user-scoped via the dual-auth dependency; the tracker calls as
+the user (forwarded session/JWT) or, service-to-service, with ``X-API-Key``.
