Ruben Fiszel 320984b92e feat(debounce): claim-based exactly-once batch consumption ...

Eliminates the rare duplicate/loss when two survivors land on one debounce
batch (a narrow push/pull race), without locking the worker pull hot path.

- migration: v2_job_debounce_batch gains consumed_at + consumed_by.
- pull side (maybe_apply_debouncing): instead of deleting the batch on consume,
  a survivor atomically claims its own row + any unclaimed siblings (stamping
  consumed_by = itself) and accumulates exactly the rows it claimed. A second
  survivor of the same batch finds its row already consumed by another job and
  runs empty (no duplicate); a re-pulled survivor recognizes its own prior claim
  and keeps its accumulated args; a never-batched job (CE/legacy) keeps its own
  args. Non-accumulate debounce paths still hard-delete their batch rows.
- complete_debounced_job (EE companion) never completes a running predecessor,
  so its in-flight run is not killed (no loss); the claim then prevents the
  duplicate the guard would otherwise allow.
- monitor: GC sweep deletes consumed batch rows past a 1h grace.

Together with the running-survivor guard this makes debounce accumulation
exactly-once. Adds tests: batch_consumed_exactly_once, repull_keeps_accumulated.
