fix: use profile_<lang>/ structure with sparse metadata overrides

Restore profile_<lang>/ directory structure from PR #155 for content
modules. Slim down each profile's metadata.toml to sparse overrides
that are deep-merged with root metadata.toml. Remove the separate
profiles/ directory — overrides now live inside profile_<lang>/.

Update cv.typ and letter.typ to deep-merge root + profile metadata.
Update all docs to reflect profile_<lang>/ paths.
