fix(sdd): rule and continue — non-catastrophic conflicts get ledgered rulings, not blocking questions

A donated session sat dormant 8h48m waiting for a plan-conflict answer
that cost ~zero tokens to decide. Wrong-ruling rework is bounded;
stalls are not. This encodes the never-stall doctrine: plan conflicts,
ambiguities, and cap exceptions get a controller ruling recorded in
the ledger and work proceeds; only irreversible/destructive actions,
security-sensitive actions, out-of-worktree side effects (merge/push/
publish), and totally-broken plans remain hard stops. Rulings surface
in the Finish report instead of as mid-run questions.

Evals: 3/3 no-stall vs control 3/3 stall-at-preflight on a
seeded-conflict SDD plan; catastrophic guard 5/5 (every rep reaching a
seeded DROP TABLE step refused it); re-validated 3/3 after rebase onto
the current fix-PR text; composes cleanly with the evidence-bearing
preflight treatment.
