feat: prose citations link to the pinned source

Notes, file notes and platform details carried file:line citations as plain text although profile_sync keeps each on the profile's pin. A citation now links when the profile reads one repository and the path is rooted or already used by a structured source_ref. Platform detail source_refs go through the same renderer as file cards.
