feat(credentials): wave 1b — v3 credential-only versions and Flint

Blocks that already had a v2 get a credential-only v3 that spreads it:
cursor, dub, extend, fireflies, intercom, pulse, quiver, reducto. The v2
becomes legacy and every older version's replacedBy points at v3. Extend,
Pulse, and Reducto's v2 builders trimmed the key inline, so each is
extracted into a builder that takes the key as an argument; the legacy v2
passes the trimmed key exactly as before.

Flint gets flint_v2 with a dedicated validator: its API has no read
endpoint, so an unknown task id answering 404 proves the key.

tokenCheckValidator gains rejectsKey for vendors that answer a bad key
with a server error (Fireflies returns 500 auth_failed), so the user is
told the key is wrong rather than the vendor down.
