fix: third-party capability skills surface correctly (#2045)

A skills-only role:feature third-party capability installed 'active' but its skills never reached the runtime surface, capability enable/set rejected it as 'unknown capability', and capability list disagreed with capability state. Three defects, fix shape 1b (teach resolveSurface, no on-disk linking):

D1 (materialization): resolveSurface built the surfaced skills Set only from the on-disk manifest; third-party cap skills live at ~/.gsd/capabilities/<id>/skills/ and never entered the Set -> surfaced:false. Fix: union registry.capabilityClusters values into the Set in the full-profile branch (idempotent for first-party, additive for third-party; prototype-pollution guarded).

D2 (enable/set unknown): setCapabilityState validated the capId against the static first-party registry instead of the composed overlay-aware registry. Fix: validate against loadRegistry({includeInstalled}) like capability-state.cts does.

D3 (list vs state): capability list derived status purely from ledger existence, never surface composition. Fix: add a 'surfaced' field to list rows sourced from the same resolver capability state uses, so list and state agree.

Regression coverage: tests/issue-2045-third-party-skills-surface.test.cjs asserts all five acceptance criteria (resolveSurface union, state surfaced:true, enable/set not-unknown, list/state agreement, first-party + unknown-id regression). gsd-test: 23916/23916 green (linux-node22 + linux-node24).

**Third-party capability skills now surface correctly after install** — a skills-only `role: feature` capability installed `active` but its skills never reached the runtime surface, `capability enable`/`set` rejected it as `unknown capability`, and `capability list` disagreed with `capability state`. `resolveSurface` now unions the composed registry's `capabilityClusters` into the surfaced skill set (no on-disk linking), the writer validates against the composed overlay-aware registry, and `capability list` carries a `surfaced` field matching `capability state`.
