Claude 5683c74629 perf(amethyst): mine on half the device's cores in the Android app
Each PoW job now races PoWPolicy.minerWorkers(cores) = cores/2 parallel
searches (at least 1) instead of a single thread, so a post on an 8-core
phone mines ~4x faster while the other half of the cores stays free for
the UI, and the total CPU budget matches the old 2-job x 1-thread pool.

- PoWPolicy.minerWorkers(availableProcessors) is the single definition of
  the per-job worker budget.
- PoWPublishQueue gains minerThreads (used by its built-in miner and
  exposed for custom mine lambdas); AppModules wires maxConcurrent = 1 +
  minerThreads = half the cores.
- PoWNostrSigner gains a workers param (default 1), covering reactions,
  reposts and reports via Account.miningSigner; the anonymous-post paths
  in the short-note and comment composers pass the same budget.
- Gift-wrap envelope mining stays single-threaded: the template
  conversion is a non-suspend hook inside the synchronous NIP-59 build.
- UI time estimates (settings picker, composer chip, broadcast banner)
  now benchmark at the queue's worker count via deviceHashesPerSecond(),
  and PoWEstimator caches one rate per worker count.
