feat(shapes): the write-path hook suggests and no longer stamps (milestone 439 step 4)

The hook used to land its evidence as `instance` rows, classified_by=hook —
a permanent verdict nobody read, and the source of the weak stamps that
poisoned two ledgers (#4608). Now the agent that wrote the code judges it at
the end of the turn, and the hook's evidence is what it is shown.

- shape_ledger.suggest_write_path_instances (was stamp_write_path_instances):
  same evidence and form gate, but it writes a PROPOSAL — proposed_snippet_id,
  basis "reference" (named) or "semantic" (resembles), score — and never a
  status. A judged row is left alone; a new shape gets an unclassified
  provisional row so the suggestion reaches the end-of-turn question as
  "looks like #N". By-name uses edges stay: a fact, not a verdict.
- The prior-art line says "looks like #N … when you judge this turn's
  shapes, say whether it is", and the result key is `suggested`.
- write_time_divergence takes `suggested`; _RESEMBLE_MIN re-documented as the
  suggestion bar and the weak-stamp line.
- reusing-code skill no longer says the pull stamps an instance.
- Tests moved to the new contract, plus a guard that nothing the hook does
  writes classified_by="hook".
