feat: machine-wide intelligence discovery and a selectable project view

[pacphi]

Summary

The dashboard's Intelligence panel previously showed exactly one project's learning telemetry, implicitly tied to whichever directory the dashboard process happened to launch from — with no way to see or compare any other project on the machine. This was a deliberate clean-break redesign (the project is still pre-release, 4.0.0-alpha line, so no backward-compatibility constraint applied): the panel now shows a machine-wide rollup across every ruflo-initialized project plus an explicitly selected, explicitly labeled detail project, defaulting to whichever was most recently active.

Source

• src/lib/dashboard/project-discovery.mjs — discoverRuvfloProjects() unions three sources into one deduplicated, most-recently-active-first catalog: ruflo's own daemon workspace registry (registryWorkspaces(), reused verbatim from daemons.mjs, now exported), a cross-reference against Observability's persisted workspace snapshots, and real cwd values read directly out of Claude/Codex transcript content via the same discoverJsonl()/bootstrapRecords() functions Observability already trusts. The third source exists because the first two turned out to be insufficient in practice — this machine's ruflo 3.34.0 install never wrote the central registry files daemons.mjs's own header comment assumed ruflo 3.28+ would, and Observability's snapshot store is deliberately privacy-sanitized and structurally never carries a resolvable path. The transcript source is what actually finds real projects on a real machine, verified against this repo's own 4 ruflo-initialized projects.
• readMachineWideIntel(projects) added to intel-history.mjs, folding readIntelHistory() across every discovered project into one { totals, perProject } rollup, keeping the lifetime patterns-learned counter and the pattern-store's current size as two distinct, never-conflated sums at machine scope. A project whose data is missing/malformed degrades to nulls/zeros rather than aborting the whole scan.
• dashboard-server.mjs's /api/status intel payload and /api/live/intelligence route redesigned around a shared ?project=<key> parameter, resolved identically by both endpoints, defaulting to the most-recently-active discovered project (never the server's own cwd, which no longer has special status). The prior server-wide singleton IntelligenceWatch is replaced by a small pool keyed by resolved project path: created lazily on a project's first SSE subscriber, stopped on last disconnect.
• client.mjs/page.mjs — an always-visible machine-wide stat row and per-project breakdown table, a project picker driving the existing 5-figure detail strip (now explicitly labeled by selected project), and live-stream resubscription on picker change.

Tests

• tests/kit/project-discovery.test.mjs — dedup/tagging across all three sources, the .claude-flow/neural filter, most-recently-active sorting, and direct coverage of the transcript source (flat Claude cwd, nested Codex payload.cwd, dedup against the registry source).
• tests/kit/intel-history.test.mjs — readMachineWideIntel's multi-project aggregation, the lifetime-counter-vs-store-entries distinction, graceful degradation, most-active-project selection.
• tests/kit/dashboard-intel-integration.test.mjs — rewritten for the new payload shape: default/explicit/fallback project selection, machine-wide aggregation, and the watcher pool's create-on-subscribe/teardown-on-last-disconnect lifecycle.
• tests/dashboard.test.cjs — updated for the new nested intel.health shape.

Docs

• ADR-0024 and docs/ddd/project-intelligence.md amended in place (no new ADR number) to describe the three-source discovery model, the corrected standing of the registry source, the shared ?project= contract, and the watcher-pool lifecycle.
• docs/ddd/ubiquitous-language.md and docs/DASHBOARD.md updated for the new shared vocabulary.

Test plan

• pnpm run check (typecheck, lint, markdownlint, build, full test suite) — green locally, 1301 tests
• Manual browser verification of picker + live subscription switching across real multi-project data
• Discovery independently verified against this repo's own real .claude-flow/ data (finds all 4 real projects)
• CI green on this PR
