Consolidate all pre-rename release notes (the retired get-shit-done-cc /
get-shit-done-redux lineage, 1.0.0 -> 1.50.0-canary.1) into one condensed,
read-only archive so the legacy 1.x version numbers no longer collide with
the current @opengsd/gsd-core line.
- Add docs/RELEASE-NOTES-LEGACY.md: rename banner, master version-index
table, condensed per-version sections (1.42.3 -> 1.0.0), and a separate
pre-release & canary builds section. Stale install commands stripped.
- Trim CHANGELOG.md to the current @opengsd/gsd-core line only; replace the
Legacy Release History block with a pointer to the archive and drop the
orphaned numbered legacy reference-link definitions.
- Remove the 10 standalone docs/RELEASE-v*.md files.
- Repoint docs/CANARY.md and docs/FEATURES.md links to the new archive.
