docs: add release-notes
What changed, and why it matters
This commit only updates release notes and simplifies a Dockerfile line by hardcoding the Go version instead of using a build argument. There is no security-relevant code change.
No action required; this is a documentation and minor Dockerfile cleanup commit with no security implications.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The diff modifies docs/release-notes/release-notes-0.21.0.md to add a release-note entry about Docker documentation overhaul, and changes docker/btcd/Dockerfile from ‘ARG GO_VERSION=1.25.5’ followed by ‘FROM golang:${GO_VERSION}-alpine’ to a direct ‘FROM golang:1.25.5-alpine’. This is a documentation and build-cosmetic change with no functional or security impact.
