fix: remove duplicate BTC_RPCPORT=8333 (use 8332) and drop build_0.1.6 artifacts

[3alpha]

Problem

docker-compose.yml declared BTC_RPCPORT twice:

- BTC_RPCPORT=8332   # added in PR #45 (8ea3d98, "add rpcport as env")
...
- BTC_RPCPORT=8333   # added in PR #48 (f0b0077, "Fix missing rpc port")

Docker Compose merges duplicate environment keys last-wins, so the
container actually received BTC_RPCPORT=8333. That is the mainnet P2P
port (and this package already maps P2P to 8340 via P2P_PORT=8340),
so the JSON-RPC server was attempting to bind the same port as the
peer-to-peer listener.

The entrypoint default in src/docker_entrypoint.sh is already
rpcport=${BTC_RPCPORT:-8332}, and EXPOSE documents 8332/8333,
so the intended value is 8332 (the mainnet JSON-RPC port).

Fix

• Remove the duplicate BTC_RPCPORT=8333 line, keeping the original
  BTC_RPCPORT=8332 from PR bump bitcoin/bitcoin to v26.2 #45.
• Drop stale build_0.1.6/ artifacts (avatar, tarballs, manifest,
  compose) that should not have been tracked in git.

Verification

After this change:

environment:
  - BTC_RPCPORT=8332
  - P2P_PORT=8340
ports:
  - "8340:8340"

bitcoin.conf will set rpcport=8332 and bitcoind will listen
for P2P traffic on 8340 — no port collision, matches the entrypoint
defaults and the standard mainnet convention.
