feat: Phase 6 — Living Taxonomy + Universal Capture

Closes two real-use gaps:
1. "APM tool" gap: work done outside Claude Code (desktop, web, phone,
   other machine) was invisible to AtoCore.
2. Project discovery gap: manual JSON-file edits required to promote
   an emerging theme to a first-class project.

B — atocore_remember MCP tool (scripts/atocore_mcp.py):
- New MCP tool for universal capture from any MCP-aware client
  (Claude Desktop, Code, Cursor, Zed, Windsurf, etc.)
- Accepts content (required) + memory_type/project/confidence/
  valid_until/domain_tags (all optional with sensible defaults)
- Creates a candidate memory, goes through the existing 3-tier triage
  (no bypass — the quality gate catches noise)
- Detailed tool description guides Claude on when to invoke: "remember
  this", "save that for later", "don't lose this fact"
- Total tools exposed by MCP server: 14 → 15

C.1 Emerging-concepts detector (scripts/detect_emerging.py):
- Nightly scan of active + candidate memories for:
  * Unregistered project names with ≥3 memory occurrences
  * Top 20 domain_tags by frequency (emerging categories)
  * Active memories with reference_count ≥ 5 + valid_until set
    (reinforced transients — candidates for extension)
- Writes findings to atocore/proposals/* project state entries
- Emits "warning" alert via Phase 4 framework the FIRST time a new
  project crosses the 5-memory alert threshold (avoids spam)
- Configurable via env vars: ATOCORE_EMERGING_PROJECT_MIN (default 3),
  ATOCORE_EMERGING_ALERT_THRESHOLD (default 5), TOP_TAGS_LIMIT (20)

C.2 Registration surface (src/atocore/api/routes.py + wiki.py):
- POST /admin/projects/register-emerging — one-click register with
  sensible defaults (ingest_roots auto-filled with
  vault:incoming/projects/<id>/ convention). Clears the proposal
  from the dashboard list on success.
- Dashboard /admin/dashboard: new "proposals" section with
  unregistered_projects + emerging_categories + reinforced_transients.
- Wiki homepage: "📋 Emerging" section rendering each unregistered
  project as a card with count + 2 sample memory previews + inline
  "📌 Register as project" button that calls the endpoint via fetch,
  reloads the page on success.

C.3 Transient-to-durable extension
(src/atocore/memory/service.py + API + cron):
- New extend_reinforced_valid_until() function — scans active memories
  with valid_until in the next 30 days and reference_count ≥ 5.
  Extends expiry by 90 days. If reference_count ≥ 10, clears expiry
  entirely (makes permanent). Writes audit rows via the Phase 4
  memory_audit framework with actor="transient-to-durable".
- POST /admin/memory/extend-reinforced — API wrapper for cron.
- Matches the user's intuition: "something transient becomes important
  if you keep coming back to it".

Nightly cron (deploy/dalidou/batch-extract.sh):
- Step F2: detect_emerging.py (after F pipeline summary)
- Step F3: /admin/memory/extend-reinforced (before integrity check)
- Both fail-open; errors don't break the pipeline.

Tests: 366 → 374 (+8 for Phase 6):
- 6 tests for extend_reinforced_valid_until covering:
  extension path, permanent path, skip far-future, skip low-refs,
  skip permanent memories, audit row write
- 2 smoke tests for the detector (imports cleanly, handles empty DB)
- MCP tool changes don't need new tests — the wrapper is pure passthrough

Design decisions documented in plan file:
- atocore_remember deliberately doesn't bypass triage (quality gate)
- Detector is passive (surfaces proposals) not active (auto-registers)
- Sensible ingest-root defaults ("vault:incoming/projects/<id>/")
  so registration is one-click with no file-path thinking
- Extension adds 90 days rather than clearing expiry (gradual
  permanence earned through sustained reinforcement)
