Merge pull request 'Process contracts — invoke by name, compose with the conversation, author as a shape' (#109) from dev into main

Operator's generalization of #2582: the benefit of nearly every stored
process is the accumulated SHAPE — steps, taxonomy, quality bar — and a
process must not force anything or overwrite the intent of the request
that invoked it. create_process now states the authoring side of the
composition contract: no embedded approach mandates, no pre-granted
approvals, clarify steps seed from the conversation instead of
re-asking it.

(All three stored processes were also audited: DRY Pass and Rulebook
Review were already propose-approve-apply with no forcing language;
both gained the seeded-clarify line — data changes, live already.)

     Resolution: numeric id → exact (case-insensitive) title → substring. On an
     ambiguous substring match, the best (most-recent) match is returned with an
     `other_matches` list so you can disambiguate with the operator.
