bear_context_set_prefix
Idempotent
Update the tag prefix for your context library, re-tagging all Bear notes with the new prefix while preserving sub-tags. Aligns qualifier tags with naming schemes like Johnny Decimal.
Instructions
Change the context library's tag prefix and re-tag every Bear note that currently uses the old prefix. Sub-tags are preserved — #context/research becomes #<new>/research. Updates both the markdown body and the CloudKit tag index, and persists the new prefix to the context config. Useful when aligning the qualifier tag with a broader naming scheme like Johnny Decimal (e.g. '10-projects'). Run bear_context_sync afterwards to refresh the library.
