Jakub Zych a9a7a328e6 refactor: hard-fork GSD -> MSD (Make Software Done)
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.

/**
* scripts/registry-schema.cjs — pure schema/vocab constants + validation +
* markdown-generation logic for the three third-party discoverability catalogs
* (issue #2182, plus #2904):
*
* - `docs/registries/capabilities.json` → "MSD Community Capability Registry"
* - `docs/registries/eos.json` → "MSD EoS Registry" (PR2)
* - `docs/registries/reviewers.json` → "MSD Reviewer Lane Registry" (issue #2904)
*
* The vocabulary constants below are ADDITIVE CONTRACTS that track the
* runtime/ADR closed vocabularies they describe — they are a documentation-
* registry-scoped mirror, not the runtime source of truth:
*
* - `LOOP_POINTS` mirrors ADR-857 "Loop Extension Points (the 12)"
* (docs/adr/857-capability-system.md §"Loop Extension Points (the 12)").
* The canonical runtime set lives in `src/loop-resolver.cts`
* (`CANONICAL_POINTS` / `CANONICAL_POINTS_FALLBACK`, derived from
* `loop-host-contract.cjs`) — changing that set requires updating this
* list too, since a registry entry's `loopExtensionPoints` describes
* which of those 12 points a third-party capability extends.
* - `HOOK_KINDS` mirrors ADR-857 Decision 4 "three hook kinds": `step`
* (runs as its own sequenced unit), `contribution` (injects into the
* core step's prompt/context), `gate` (checks and optionally blocks).
* - `INTERFACE_POINTS` mirrors ADR-1239 "The six interface points" (the
* Host-Integration Interface integration surface): command/workflow
* invocation, agent dispatch, model invocation, lifecycle hooks,
* state+config IO, artifact surface.
* - `PROFILES` mirrors ADR-1239 "Host-capability profiles (negotiation
* baselines)": `programmatic-cli`, `declarative-cli`, `ide`.
* - `AXES` mirrors ADR-1239 "the eight negotiated axes" (the negotiated
* capability schema exchanged at `initialize`): `embeddingMode`,
* `commandSurface`, `dispatch`, `modelMode`, `hookBus`, `stateIO`,
* `transport`, `runtime`. Seven of the eight are closed enums here;
* `dispatch` is ADR-1239's structured negotiated object
* (`{ namedDispatch, nested, maxDepth, background, subagentToolkit }`) —
* this registry accepts a free-form human summary string instead, so it
* carries the `AXES_FREE_STRING` sentinel rather than an enum array.
* `OPTIONAL_AXES` adds one further, OPTIONAL key on top of those eight:
* `effortSurface` (ADR-1239 amendment #2481). An entry may omit it
* (every entry published before the amendment stays valid) or declare
* it as `argv` | `none`, mirroring `HOST_INTEGRATION_AXES.effortSurface`
* in `src/host-integration.cts`.
* - `CAPABILITY_REQUIRED` / `EOS_REQUIRED` / `REVIEWER_REQUIRED` mirror the
* required top-level fields for each entry type, including `enginesMsd`
* (ADR-1244 D1 "Versioned capability manifest" — the `engines.msd`
* semver-range gate, modelled on VS Code's `engines.vscode`).
* - `REVIEWER_LANE_TRANSPORTS` / `REVIEWER_EVIDENCE_CLASSES` /
* `REVIEWER_SLUG_RE` / `REVIEWER_FLAG_RE` / `REVIEWER_SECTION_MAX` mirror
* the ADR-2782 reviewer-lane vocabulary (`capability-validator.cjs`) for
* the `reviewer` entry type's `interactions` sub-object (issue #2904).
*
* This module is pure — no `fs`/`process`/child-process access — so tests
* can `require()` it directly and assert on structured return values.
* `scripts/validate-registry.cjs` and `scripts/gen-registry.cjs` are the thin
* CLI wrappers that perform I/O around these functions.

// `REVIEWER_SLUG_RE` deliberately does NOT reuse the registry's kebab-case `id`
// grammar. `LANE_SLUG_RE` permits underscores AND a leading digit —
// `lm_studio`, `llama_cpp`, `4o-mini` are real shipped lane slugs — and
