Make public worker share links installable via Floom skills CLI

[federicodeponte]

Problem

Public worker share pages now expose source/download and an agent prompt, but the skills CLI rejects worker share links as install links.

Verified command on 2026-07-01:

npx -y @floomhq/skills install https://floom.dev/s/fls_3IKltS7cAUU3v1XIefwIcUkB --agent codex --dry-run

Result:

✗ That doesn't look like a Floom share link. It should look like: https://floom.dev/s/fls_xxx

The URL is a valid public worker share link and resolves through https://floom.dev/s/... to https://floom.dev/app/s/.... Its API payload includes entity_type: worker, shared_by, overview, and 5 files.

Expected

One of these becomes true:

• @floomhq/skills install <public-worker-share-url> --agent codex installs a worker-backed skill wrapper for Codex/Claude/Gemini/OpenCode, or
• the CLI returns a specific unsupported-entity message that tells users to use the agent prompt/import flow instead of saying the valid fls_ link shape is invalid.

The public page now verifies these production-visible items:

• sharer identity
• overview
• source files with Copy source and Download
• setup tab with Copy prompt
