Mechanical rename produced by scripts/msd-rename.cjs: gsd/Gsd/GSD -> msd/Msd/MSD
across contents and paths, upstream package/repo coordinates -> @golem15/msd-core
and golem15com/msd-core. Deep links into upstream history, sibling upstream
packages, the GSD-2 import feature, CHANGELOG.md and .changeset/ are kept as-is.
Hand edits on top: MSD block-letter banner and logos, LICENSE copyright line,
package/plugin identity, regenerated lockfile, install-tree fixtures, derived
registries and benchmark baseline; migration checksum baseline re-locked
(MSD keeps its own install state, so no install had applied the old sums);
sort-order and regex-escaped expectations in tests adjusted.
Implements the three pure functions in registry-schema.cjs (isValidGsdRange,
validateEntries, renderMarkdown) that were stubbed in the previous commit, turning
the red suite green: strict per-type schema validation (capability + eos), a
self-contained engines.gsd range validator (no semver dep), and deterministic
Markdown generation with shields.io release badges + per-entry Discussion links.
Regenerates docs/registries/capability-registry.md and adds the Added changeset.
Also hardens the isValidGsdRange fast-check property (letters-only major) so it
cannot intermittently generate a valid prerelease range and flake.
Closes#2182
