Proposal: configurable global skill paths

Heyy 🖤 Thx a lot for this amazing and inspiring project!

Since PRs are limited don't know whether you'd be offended to discuss it and for an issue to be opened instead

Jcode is already great out of the box with /skill and not impacted by Skill Token Context Problem,
so did a trial PR here https://github.com/Neved4/jcode/pull/1 that adds two small environment variables:

• JCODE_SKILL_PATHS for the usual one-directory-deep layout
• JCODE_SKILL_PATHS_RECURSIVE for recursively organized skill collections

Both work during startup and reload and should follow jcode existing skill perms and precedence logic
Recursive discovery should be bounded and deterministic, skip common noisy directories, avoid dir symlinks, and not scan duplicate paths twice, or that's the idea, but you know your codebase much better than we do! 🙈

Kept visibility and prompt out of scope, since that’s already being discussed in #141

Any feedback much appreciated,
Cheers, keep rocking!!

Start at the skill discovery entry points used during startup and reload, then trace the existing /skill permission and precedence logic. The linked trial PR and this proposal describe the expected JCODE_SKILL_PATHS and JCODE_SKILL_PATHS_RECURSIVE behavior; done means both paths integrate with that logic while bounded recursive discovery remains deterministic and avoids duplicate or symlinked directories.
