Add agent skills to the registry catalogue alongside modules and
templates, following the agentskills.io specification with proper
frontmatter metadata (license, version, author, tags).
- Add registry/coder/skills/coder-modules/ and
registry/coder/skills/coder-templates/ as catalogue entries,
each with SKILL.md (full spec frontmatter + body) and README.md.
- Update .agents/skills/ frontmatter to match catalogue versions.
- Update CI/CD workflows and scripts to support skills:
- deploy-registry.yaml: add skills path trigger
- release.yml: detect skills vs modules for changelog path
- version-bump.yaml: add skills path trigger
- version-bump.sh: include skills in change detection
- tag_release.sh: scan skills directories and extract version
from SKILL.md frontmatter
## Description
Add two Claude Code skills for the Coder Registry: `coder-modules` and
`coder-templates`. These skills guide AI agents through creating and
updating registry modules and workspace templates, covering scaffolding,
Terraform patterns, testing, README standards, icon management, version
bumps, and newer features like presets, prebuilds, and task-oriented
templates.
