fix(sync): process-skill triggers invoke by name only — resemblance offers, never substitutes

Scribe issue #2582: the sync wrote "Use when {title}-type work is
requested" into every generated process skill, so a bespoke live prompt
that merely resembled a stored Process got the Process's canned
procedure — and inherited approvals embedded in its body (the Drift
Audit's fan-out opt-in) that the conversation never granted. Observed
live: an explicit systems-review request with its own constraints was
answered with the Drift Audit clarify menu recommending ~15 parallel
auditors.

New trigger contract, both variants: follow verbatim only when invoked
by name; on mere resemblance the live instructions govern — offer the
process, ask before following, and never inherit embedded approvals the
operator hasn't granted in this conversation.

(The Drift Audit process record itself was also rewritten to a
sequential in-context walk — data change, live already, recorded in
the same issue.)
