saubyk 6e55059fe2 Add an Eclair node to the regtest docker fixture ... Completes backend coverage of RTL's three implementations in the docker/ dev fixture: an eclair node (polarlightning/eclair 0.13.1) joins the three LND nodes and the CLN node, wired to RTL over its HTTP API with basic auth, and the seed opens an eclair->bob channel (3.5M sats, 1M pushed), sends two direct payments and leaves one open invoice. Non-obvious plumbing this needed: - polarlightning/eclair instead of acinq/eclair: the official image is amd64-only (useless on Apple Silicon) and its newest versioned tag is years stale; Polar builds the same ACINQ source multi-arch. - Eclair has no on-chain wallet of its own -- it drives a bitcoind wallet. A new eclair-wallet-init container creates a dedicated "eclair" wallet before the node starts; without it eclair attaches to "the default loaded wallet", i.e. the rtldev mining wallet. - bitcoind now also publishes a zmqpubhashblock endpoint (28336): eclair's bitcoind.zmqblock consumes the hashblock topic, not the rawblock one LND uses. Wired to rawblock, eclair never sees new blocks and channels hang in WAIT_FOR_FUNDING_CONFIRMED. - Eclair confirms channels at 8 blocks (channel.min-depth-blocks), not 6, and 'open' returns before the funding tx is broadcast -- the seed waits for the mempool and mines 8 blocks for this channel. Adds a bin/e-cli helper (eclair-cli with the API password), updates the README, and verified end-to-end: seed completes, the channel reaches NORMAL, both payments settle, and RTL's /rtl/api/ecl endpoints return the node, channel and invoice data.		2026-07-19 22:01:23 -07:00
