feat(reuse): recording gets a seam — the prior-art hook asks for create_snippet when duplication is proven and unrecorded (#2664)

Zero snippets were ever recorded outside sessions already thinking about
snippets: the read side had a real seam (the PreToolUse hook) and the record
side had a trailing clause of a floor bullet. The trigger moment — 'I just
wrote the second copy' — is mid-Write/Edit, so the nudge now rides the same
hook: when the local arm proves the definition exists elsewhere in the repo
AND Scribe returned no record of it, the context block asks for
create_snippet. Both gates or silence, so a brand-new helper and an
already-recorded one stay nudge-free.

Floor bullet promoted to name the trigger moments (extract, hoist, second
copy); guarded by test the same way the Systems reflex is. Plugin 0.1.29 so
the cache picks up the hook (#2209).
