Phase D2 of plan 2026-08-19: single package, single install, single command.
The framework installer already treats skills/** as a shipped, manifest-owned
framework subtree, so the folded skills now install into
$MOSAIC_HOME/skills with the rest of the framework — no second repository,
no separate sync step:
- mosaic-sync-skills (bash + powershell): the fetch machinery is gone (clone,
pull, dirty-state migration, rsync from sources/agent-skills). The script
now only links installed skills into runtime homes. --link-only is a compat
no-op; --no-link exits having nothing to do.
- catalog.ts: the sources/agent-skills fallback is dead and removed.
- install.sh, launch.ts, defaults/README.md, README.md, skills/README.md:
references to the second repo rewritten to describe the shipped path.
Verified: clean install into a fresh MOSAIC_HOME produces 102 skills with no
sources/ directory; the linker then links the selected skills into the four
runtime homes with no git involvement.
