Tom Boucher 88d6b392af fix(#2362): materialize third-party capability skills on opencode/kilo install (#2434)
* fix(#2362): materialize third-party capability skills on opencode/kilo install

installOpencodeFamilyArtifacts/installOpencodeFamilySkills never received
the capability registry, so a registered+surfaced+active third-party
capability skill was silently dropped by the OpenCode/Kilo combined-family
INSTALL path (registry said surfaced:true, disk had nothing). Thread
capabilityRegistry through and reuse the existing #2322 seam's exported
helpers (readInstalledCapabilitySkill, capabilityClusterStems,
CAPABILITY_SKILL_MARKER) to fill in third-party skills after the first-party
loop, with the same guarantees: registry-bound ownership, first-party-wins,
full/'*' sentinel support, and graceful degradation on a missing/corrupt
capability skill.

* test(#2362): cover the tiered (non-'*') profile candidateStems branch

Review found the new third-party capability-skill fill-in for OpenCode/Kilo
had zero coverage of the tiered-profile path — all 12 regression tests only
exercised the '*' full-profile sentinel. Adds a case that resolves a
`standard`-tier profile through a synthetic registry (mirroring the seam's
own __registryFor pattern) and asserts the resulting concrete Set still
materializes the registered capability skill, with its prune-parity marker,
alongside the tier's first-party skills.

Also adds the .changeset/ fragment this fix was still missing.

Fixed 2434

Installed third-party capability skills now materialize on OpenCode and Kilo — capability install + capability set --runtime opencode (or kilo) could report a capability as installed: true, surfaced: true, active: true while its skill was never written to skills/gsd-<stem>/SKILL.md: the OpenCode/Kilo combined-family install path never called the seam #2322 fixed for other runtimes. Installed capability skills now materialize the same way there too, bound to their declaring capability, with first-party skills always winning a name collision. (#2362)
