Add Kiro as a skill-supporting client

[samuv]

Summary

Enables Kiro as a skill-supporting client in ToolHive.

• Skills install to ~/.kiro/skills/<name> (user scope) and <project>/.kiro/skills/<name> (project scope) — matching Kiro's native skill path convention
• No platform prefix needed; paths are consistent across Linux, macOS, and Windows

Documentation reference: Kiro Agent Skills

Type of change

• New feature

Test plan

• Unit tests (task test)
• Linting (task lint-fix)

Changes

File	Change
pkg/client/config.go	Add SupportsSkills, SkillsGlobalPath, SkillsProjectPath to the existing Kiro config entry
pkg/client/skills_test.go	Add Kiro to fixture, TestSupportsSkills, TestListSkillSupportingClients (12 → 13), and TestGetSkillPath (2 new cases)

Does this introduce a user-facing change?

Yes — thv skill install --clients kiro (or --clients all) now works. Skills land in ~/.kiro/skills/ so Kiro picks them up automatically.

LGTM — straightforward addition of Kiro as a skill-supporting client, following the same pattern as recent similar additions.

Extended reasoning...

Overview

The PR adds skill support to the existing Kiro client entry in pkg/client/config.go (3 lines: SupportsSkills, SkillsGlobalPath, SkillsProjectPath) and updates pkg/client/skills_test.go with corresponding fixture data, a TestSupportsSkills case, a count bump in TestListSkillSupportingClients, and two TestGetSkillPath cases.

Security risks

None. This is a path configuration change — it only adds a new directory path (.kiro/skills) where skill files are installed. No auth, crypto, or permission logic is touched.

Level of scrutiny

Low. The change is entirely mechanical and follows the identical pattern used when Goose, Gemini CLI, Amp, and others were added. The path convention (.kiro/skills/) is consistent with Kiro's documented conventions and requires no platform prefix (same approach as Cursor, ClaudeCode, etc.).

Other factors

The only bug found is a nit: the descriptive comment in TestListSkillSupportingClients lists clients in wrong alphabetical order ("Kiro, KimiCli" should be "KimiCli, Kiro" since kimi-cli < kiro lexicographically). The runtime assertion is unaffected and passes correctly. This is already captured as an inline comment. It does not warrant blocking the PR.
