feat(cli): --quiet/--yes globals; echo resolved write target; gate non-local destructive writes (#243)

RFC-011 Decision 9. Writes echo their resolved target + access path to stderr (suppress with --quiet). Destructive writes (cleanup, overwrite load, branch delete) against a non-local scope require consent: --yes, a TTY prompt, or a hard refusal for non-TTY/--json runs. Local file:// writes unaffected.

backstop, so it does as much as it can and converges on re-run. The CLI reports
any failed tables; rerun `cleanup` to retry them.
- CLI guards with `--confirm`; without it, prints a preview line.
- **Non-local consent (RFC-011 D9).** Against a non-local target (an `s3://` store/cluster), `cleanup` additionally requires `--yes` on top of `--confirm`: a TTY is prompted, and a non-interactive run (no TTY, or `--json`) refuses rather than destroying. A local (`file://`) target needs only `--confirm`. The same `--yes` gate applies to overwrite `load` and `branch delete`; every maintenance run echoes its resolved target to stderr (suppress with `--quiet`).
- **Recovery floor:** `--keep < 3` may garbage-collect versions that crash recovery needs as a rollback target. Default `--keep 10` is safe.
- **Orphaned-branch reconciliation:** before the version GC, cleanup reclaims any per-table or commit-graph branch absent from the manifest branch list. These orphans arise when a `branch_delete` flips the manifest authority but a downstream best-effort reclaim does not complete (see [branches-commits.md](../branching/index.md)). The reconciler is idempotent (it no-ops once nothing is orphaned), runs regardless of the `keep_versions` / `older_than` values (those gate version GC only), and never reclaims `main` or system-branch forks. Reclaimed forks are logged.
