Move skills into apps/skills/, drop override + sync layers

Skills now ship with the app under /apps/skills/ (sibling of /apps/x).
Forge bundles the directory into Resources/skills/; main resolves it via
process.resourcesPath in production and a workspace-relative path in dev,
then registers it in the DI container. The runtime reads SKILL.md files
directly from the bundle — no copy to ~/.rowboat/skills/, no GitHub
tarball sync.

Drop the override layer (FSSkillsRepo, SkillOverride, edit/diff UI,
skill-update notification) since skills are now read-only and only ship
with app updates. Resolver simplifies to a single source.

Add a placeholder substitution layer so skills that need live data
(currently `tracks`, with {{TRACK_BLOCK_SCHEMA}}) keep dynamic content
without depending on TS-module evaluation.
