Adds real-time block detection via ckpool log tailing and a push channel for the upcoming Svelte UI, all stdlib-only: - logmon.Tailer follows ckpool.log with rotation/truncation survival (inode + size tracking) and parses "Solved and confirmed block N" into BlockEvent values. - state.Aggregator grows a 256-entry block ring, an OnRefresh hook, and IngestBlockEvents which best-effort enriches events with the block hash via bitcoind getblockhash. - httpapi.Hub implements RFC 6455 from scratch (SHA1 handshake, unmasked text frames out, masked frames in, ping keepalive, per-client write mutex, slow-client drop) so we don't pull in a ws dependency before we can go mod tidy. - New routes: GET /api/blocks and GET /api/ws. Snapshot pushes fire on every poll tick and immediately on block-solve. ZMQ hashblock subscription and SQLite persistence are deferred to Phase 2b.5 once the s9pk packaging repo exists and we have a real build environment for adding Go deps.

// kamado-api is the middleware that sits between ckpool-solo and the
|
|
// Kamado dashboard. It polls ckpool's Unix socket API, calls bitcoind
|
|
// over JSON-RPC, and serves the merged state over REST (WebSocket push,
|
|
// SQLite persistence, ZMQ and log-tailer-based block detection land in
|
|
// a follow-up commit).
