FN-6705: add plugin activation analytics

Record plugin activation events and expose them to Command Center analytics. - Add plugin activation persistence, aggregation helpers, and exports. - Record load/reload activation events through the plugin loader and store APIs. - Surface plugin activation counts in the Command Center Ecosystem area and API route. - Cover migrations, aggregation behavior, plugin loader recording, route auth, UI rendering, and quarantined flaky suites.

 Key server capabilities:
 - REST APIs for tasks, git, GitHub, agents, missions, planning, automations/routines, settings
 - System stats snapshot and vitest process controls APIs (`GET /api/system-stats`, `POST /api/kill-vitest`) exposing dashboard process/system telemetry (including app CPU percentage and host memory rendered as numeric values, radial gauges, and trend sparklines in the Command Center System area), task/agent aggregates, and manual vitest process termination
- Command Center analytics APIs (`GET /api/command-center/tokens`, `/tools`, `/activity`, `/productivity`, `/team`, `/github`, `/signals`, `/live`) are project-scoped dashboard routes. `/productivity` reads Lines changed from nullable `task_commit_associations.additions`/`deletions` merge-time diff stats and keeps the unavailable sentinel when no in-range association has stats. `/signals` aggregates real local `incidents` rows for total/open/resolved counts, MTTR, and source/severity/status breakdowns and returns honest empty/unavailable sentinels instead of synthetic signal volume.

 - Remote access APIs (`/api/remote/*`) for provider config, activation, tunnel lifecycle, status, token issuance, authenticated URL generation, and QR payload generation
  - Operational runbook (prereqs/security/troubleshooting): [`docs/remote-access.md`](./remote-access.md)
  - `/api/remote/tunnel/start`, `/api/remote/tunnel/stop`, and `/api/remote/tunnel/kill-external` cover tunnel lifecycle and external funnel cleanup.

@@ -669,7 +669,7 @@ Features:
 - **Activity** tracks sessions, messages, active nodes, active agents, agent heartbeat runs, and stickiness. Agent-run sheets show total, active, completed, and failed runs for the selected range, and the Agent runs/day sparkline trends runs by `agentRuns.startedAt`. The area keeps the existing live animated line charts for messages/day, active agents/day, active nodes/day, and combined throughput/day (`messages + active agents + active nodes`), and adds a recharts multi-series line graph for messages, active agents, and agent runs plus an agent-run outcome pie from the existing `agentRuns` split. These charts reuse the existing activity analytics endpoint, refresh on a bounded 15-second cadence while mounted, keep the previous data visible during refreshes, and disable decorative draw-on motion for reduced-motion users.
 - **Productivity** separates outcome counters (commits and pull requests) from volume proxies such as modified files, lines changed, and files by language. It keeps the files-by-language bar and adds a language-share pie from `ProductivityAnalytics.byLanguage`. There is intentionally no productivity line chart because the current productivity response has no per-day throughput or completion time series; no new endpoint is called.
 - **Team** shows a per-agent analytics table plus tokens-by-agent and tasks-done-by-agent charts, and adds a real token-share pie from the same per-agent token totals. Metrics come only from the project-scoped `tasks` and `agents` tables: token totals and estimated cost are summed from the `tokenUsage*` columns by `assignedAgentId`, files changed counts parsed `tasks.modifiedFiles` paths, tasks done counts `column = 'done'` moves in the selected range, and in-progress / in-review values reflect current task columns. Agent name, role, and live state come from the `agents` table; deleted-agent task history falls back to the raw agent id instead of crashing. The tab uses `/api/command-center/team`, adds no schema, never calls GitHub, and intentionally leaves per-agent issues filed/fixed to FN-6653. Team has no per-day analytics series today, so it intentionally does not render a line chart or fabricate a trend. Decorative chart reveal motion uses duration tokens and is disabled for reduced-motion users.
- **Ecosystem** shows active model breadth and per-model task activity; unavailable plugin-activation metrics render as unavailable rather than zero. It reuses the tokens analytics endpoint grouped by model, adds a task-share-by-model pie from `TokenAnalytics.groups`, and renders a tokens/tasks trend line when `TokenAnalytics.series` buckets are present; if series buckets are absent, no synthetic trend is shown.
+- **Ecosystem** shows active model breadth, per-model task activity, and real plugin activations for the selected range. Plugin activation counts come from project-scoped plugin/extension load events via `/api/command-center/plugin-activations`; if no activation rows exist in range, the metric renders unavailable (`—`) rather than fabricating zero. The tab still reuses the tokens analytics endpoint grouped by model, adds a task-share-by-model pie from `TokenAnalytics.groups`, and renders a tokens/tasks trend line when `TokenAnalytics.series` buckets are present; if series buckets are absent, no synthetic trend is shown.
 - **GitHub** shows local GitHub issue flow for the selected range: **Filed by Fusion** counts tasks with a persisted `githubTracking.issue`, **Fixed by Fusion** counts tasks imported from GitHub source issues (`sourceIssueProvider = "github"`) that are currently in `done`, using the persisted `sourceIssueClosedAt` / `TaskSourceIssue.closedAt` close time when the reconciler has observed it. Rows that predate the field or have not been observed closed fall back to task `updatedAt` as the documented completion-time approximation; Fusion never fabricates a close timestamp and this analytics path never calls GitHub, the `gh` CLI, or any external network source. To make historical fixed dates exact, use **Backfill exact close times** in the Fixed by Fusion card; the dashboard calls the project-scoped manual `POST /api/git/github/backfill-source-issue-closed-at` endpoint in `{ offset, limit }` batches until `hasMore` is false, then surfaces the accumulated `scanned`, `filled`, `skipped`, and `errors` counts. The endpoint fetches real GitHub `closed_at` values once, fills only missing `sourceIssueClosedAt` values, and never runs automatically or from analytics-time rendering. The area shows filed/fixed/net stat cards, a filed-vs-fixed pie, a filed/fixed recharts trend line, existing daily sparklines, and a by-repository bar breakdown.
 - **Signals** is backed by the project-scoped `/api/command-center/signals` endpoint, which aggregates real rows from the local `incidents` table. It shows total/open/resolved counts, MTTR when resolved incidents have enough timestamps, and source/severity/status breakdowns; an empty incidents table renders honest zero counts with MTTR unavailable rather than fabricated signal volume. It adds an open-vs-resolved status pie from the same response. Signals has no per-day series today, so it intentionally does not render a line chart or fabricate a trend. External connectors that ingest third-party signals into incidents are tracked separately in FN-6706.
 - **System** is the canonical system-telemetry destination. It reuses `GET /api/system-stats` with no new endpoint, renders live radial gauges for app CPU, host memory, and heap usage, keeps a small client-side rolling buffer for CPU/memory/heap trend sparklines, adds a recharts CPU/memory/heap line from that same rolling buffer, and adds a task-by-column pie alongside the existing tasks-by-column and agents-by-state bars. The Vitest process count, manual kill confirmation, auto-kill toggle, threshold controls, and last-auto-kill timestamp moved here unchanged; the standalone System Stats modal and its desktop Header/mobile More affordances were removed.
