Add 'templates' command to list bundled templates (discoverability for apply-template)

[renezander030]

Summary

capcut-cli ships several bundled templates (templates/*.json — caption-pop, lower-third, hook-question, gold-title, end-card, subscribe-cta) and supports apply-template / save-template. But there's no way to list the available templates from the CLI — a user has to read the repo to discover what they can apply. A capcut templates command would close that loop.

What to do

Add a templates command that lists template slugs the CLI can resolve, so apply-template is discoverable:

$ capcut templates
caption-pop    word-highlight pop captions
lower-third    name/title lower third
hook-question  opening hook question card
gold-title     gold title card
end-card       end / outro card
subscribe-cta  subscribe call-to-action

• List the bundled templates (resolve the shipped templates/ dir relative to cliDir, the same way apply-template locates them).
• Honor the global --json default convention used by the other inspect commands (machine-readable JSON unless -H/--human) so agents can enumerate templates programmatically.
• A one-line description per template is a nice-to-have (can be derived from the slug if no metadata exists).

Acceptance

• capcut templates lists every template apply-template can resolve.
• capcut templates -H prints a human table; default output is JSON (consistent with info/tracks/etc.).
• Add a test under test/ (*.test.mjs).
• Documented in README.md / docs/.

Pointers (verified against master)

• Single entry point src/index.ts; commands like enums/doctor are handled with early if (cmd === "…") checks — follow that pattern.
• Bundled templates live in templates/ at the package root; apply-template already resolves them via cliDir.
• Zero runtime dependencies (Node >= 18).

Good first issue — mirrors the existing enums command, self-contained, immediately useful.

hi @renezander030 . Can I please work on this issue.

Thanks!

Thanks @CaptainLevi25 — assigned to you! 🙏

A few pointers so your PR passes CI on the first try:

• Mirror the existing enums command — it's the closest pattern. Handle templates with an early if (cmd === "templates") in src/index.ts (commands are dispatched inline there; there's no src/commands/ dir).
• List the bundled templates by resolving the shipped templates/ dir relative to cliDir (the same way apply-template already locates them) — don't hardcode the names.
• Honor the global --json default convention: machine-readable JSON unless -H / --human (consistent with info / tracks / enums).
• Please add a small test under test/ (*.test.mjs, helpers in test/helpers/), plus a line in the HELP constant and a note in README.md / docs/.

CI runs Biome lint + node --test across Node 18/20/22, so run npm test and npm run lint locally before pushing. Shout if anything's unclear — happy to help you get it merged!
