Fix #1658: Add commands_subdir field to support non-standard agent directory structures (#1660)

- Added commands_subdir field to AGENT_CONFIG for all agents
- Updated install_ai_skills() to use commands_subdir instead of hardcoded 'commands'
- Fixed --ai-skills flag for copilot, opencode, windsurf, codex, kilocode, q, and agy
- Bumped version to 0.1.5
- Updated AGENTS.md documentation with new field

Affected agents now correctly locate their command templates:
- copilot: .github/agents/
- opencode: .opencode/command/ (singular)
- windsurf: .windsurf/workflows/
- codex: .codex/prompts/
- kilocode: .kilocode/workflows/
- q: .amazonq/prompts/
- agy: .agent/workflows/

All 51 tests pass.
