feat: gate triage sources on a per-project :TRIAGE_SOURCES: declaration

The general triage plugins (personal Gmail, cmail, calendar, Telegram, GitHub PRs) are template-synced into every project, so the old "plugins present" probe self-activated triage everywhere. The sentry live trial caught it reaching personal inboxes from a project that isn't a triage target. Now a general plugin activates only when the project names its basename in a :TRIAGE_SOURCES: line in notes.org Workflow State. A project-specific plugin stays active by presence. The gate lives in triage-intake Phase 0, so it fixes the interactive over-pull too, and sentry's pass-3 probe reads the same signal.

Presence is capability, the declaration is activation. A project that declares nothing and owns no project plugin pulls nothing. Migration handoffs went to home and work. rulesets correctly declares nothing.

Edits to =~/org/roam/inbox.org= take the roam-write lock + =capture-guard=. Probe: the roam clone or a project =inbox/= exists. Tidying the shared roam inbox is allowed from *any* project session, work included — it's housekeeping on a shared resource, not a durable KB-node write, so the work-denylist doesn't gate it (=knowledge-base.md=). Never park it as a cross-project boundary crossing.

Mere presence of the template-synced general plugins does *not* activate the pass; a project that declares no sources probe-skips (see =docs/specs/2026-07-20-triage-source-activation-spec.org=).
