Replace the flat copy-list staging with a manifest-driven copy plan:
- buildCopyPlan maps declared skills/agents/commands and string-typed
Claude-Code surfaces into canonical install slots, copies conventional
top-level metadata, and drops anything not covered (no more leaking of
tools/, website/, .github/, etc.).
- rewriteManifestPaths emits a plugin.json whose paths point at the
canonical post-install locations, keeping the on-disk manifest
self-consistent inside _bmad/<code>/.
- stageCopyPlan stages the plan plus synthesized files (rewritten
plugin.json) into the tmp dir for the atomic swap.
install.mjs and update.mjs switch to the new plan/skillDestDirs flow and
drop the now-unused copy-list helpers.
