Phase 5: iteration & polish (visualizations, goal history, smart tagging)

Final roadmap phase. No DB migration — it reads data already captured.

- Goal-evolution history: GET /discovery/profile/me/goal-history derives a
  per-goal timeline from the profile_revision snapshots (pure aggregator in
  app/services/profile_history.py).
- Smart tagging: POST /discovery/integration/suggest-foundation suggests which
  foundation a task builds toward + rationale/confidence (FoundationTagger,
  app/services/tagging.py). Suggestion only; the person confirms by posting the
  task mapping.
- Deeper goal-refinement: the reflect loop accepts an optional focus ("goals")
  that steers the coach toward sharpening goals — still mirror, not compass.
- Visualizations: visuals.html renders an Ikigai Venn and an Enneagram diagram
  (plain-language callouts, not the raw type number) plus the goal-evolution
  timeline; linked from profile.html.

Tests: 99 passing (added pure goal-history tests, goal-history + suggest
endpoint tests, reflect-focus passthrough; run in-container). README updated.

This completes the ImpactFlow Vision roadmap (Phases 1-5) on the Discovery side.
