Claude 8988c98308 feat: add NIP-13 proof-of-work publishing with a fire-and-forget mining queue
Implements user-facing PoW publishing (#3317) on top of the existing
quartz miner:

- quartz: PoWMiner.run gains a cooperative isActive cancellation hook
  (checked every ~VALID_BYTES^2 hashes); PoWNostrSigner decorator mines
  kind-scoped templates pre-signature so it composes with every signer;
  GiftWrapEvent.create/NIP17Factory can mine the outer ephemeral-key
  wrap (never the seal/rumor); NostrSignerWithClientTag exposes
  prepareTags so mining runs over the final tag set.
- commons: PoWPublishQueue (FIFO, capped worker pool on
  Dispatchers.Default, per-job cancel, in-memory only — unmined posts
  are lost on process death, logged) and PoWPolicy (kind-group
  categories with a hardcoded NEVER list: auth, zap requests, NWC and
  bunker RPC, HTTP/Blossom auth, drafts, metadata and lists, OTS).
- amethyst: per-account synced settings (difficulty Off/16/20/24/28 or
  custom, per-category checklist) in Compose Settings; Post enqueues the
  template and returns immediately; reactions, reposts, reports, private
  notes, DMs and long-form route through the same shouldMine gate at
  their existing choke points; per-post PoW override chip in the
  composer options row; "Mining proof of work… (N in queue)" phase with
  per-job cancel in the broadcast banner.

Scheduled posts and anonymous posts mine against the correct key
(scheduled posts skip mining in v1); the client tag is applied to the
template before mining so signing never invalidates the nonce.
