SPM: wire local plugins correctly — add Package.swift to each plugin's files array

Root cause of the SPM runtime regressions (call/chat push when closed, photo save):
our local file: plugins didn't function because their package.json `files` array
omitted "Package.swift", so npm can drop it from node_modules on install → cap sync
can't wire the plugin into the CapApp-SPM package → the plugin isn't loaded at
runtime. Official plugins all list Package.swift in files; ours now do too.

Also add build-log diagnostics (node_modules symlink/copy + Package.swift presence,
and the generated CapApp-SPM/Package.swift) so the wiring is provable, not guessed.

Reapplies the SPM migration (Step B) that was reverted.
