satoshiandClaude Opus 4.6 bd0b1b0318 Phase 2a: kamado-api Go middleware (core MVP)
Go 1.22 module that polls CKPool's Unix socket control API, queries
Bitcoin Core over JSON-RPC, merges both into a thread-safe snapshot, and
serves it over REST. Layout:

CKPool stores hashrate as "dsps" (diff shares per second); we convert
to H/s via the 2^32 constant used by GoBrrr-Pool and other clients.
Every stat CKPool exposes to its socket API is surfaced — useragent,
IP, per-client diff, per-worker best diff — closing the gap against
Bassin which only reads the 60-second stats files.

Dockerfile does a CGO_ENABLED=0 static build on golang:1.22-bookworm
with -trimpath -ldflags=-s -w. docker-compose now runs both ckpool and
kamado-api, sharing a named volume for /run/ckpool so the API can
dial the stratifier socket directly.

Deferred to Phase 2b (called out in README):
  - Bitcoin Core ZMQ hashblock subscriber
  - WebSocket push for real-time UI updates
  - SQLite persistence (block history, best-share history)
  - CKPool log tailer for "Solved and confirmed block" detection

Tests and build NOT run in this commit — Go isn't installed in the
dev environment. Run `make api-test` or `make api` to verify.

# Kamado Pool — development compose
#
# Spins up ckpool-solo and kamado-api pointing at a bitcoind. Expects
# bitcoind to be reachable at the host/port set in the env blocks below.
# For local testing, run bitcoind on regtest/testnet4 and set these via .env.
#
# ckpool and kamado-api share the `ckpool-sock` named volume so the API
# can dial /run/ckpool/stratifier directly.
