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.

/**
* Tests for the Windows npm resolution platform gate.
*
* Background (issue #3103, PR #3102):
* On Windows, `npm` ships as `npm.cmd`. Node's spawn does not apply PATHEXT
* resolution and fails with ENOENT. The fix is to spawn through a shell on
* Windows (cmd.exe resolves npm.cmd via PATHEXT). On POSIX, `npm` resolves
* without a shell, so spawning `/bin/sh -c` is pure overhead and changes
* signal / exit-code semantics — undesirable.
*
* Relocation (#498): the SessionStart worker no longer spawns npm itself. It
* delegates the latest-version lookup to check-latest-version's
* `checkLatestVersion()`, which routes through `execNpm` in the shell-command
* projection seam. The PR #3102 contract therefore now lives on `execNpm`.
* This test locks it there, and additionally locks that the worker does NOT
* re-introduce a direct npm spawn (which would re-open the gate question in a
* second place).
*
* Source-grep policy: these structural assertions read source via readFileSync.
* The behavior (Windows-only shell resolution) is platform-gated at runtime and
* cannot be reached on POSIX CI without a Windows lane; a structural assertion
* is the minimum-cost contract.

* Regression test for #378 / #498: the SessionStart update worker must end up
* querying the SCOPED package name (@golem15/msd-core) when it asks
* npm for the latest version.
*
* Background (#378): the worker once hardcoded the unscoped 'msd-core',
* which 404s from the registry, leaving update_available permanently false.
*
* Original #378 fix derived the name from `require('../package.json').name`.
* That is broken at runtime (#498): no package.json in the installed tree
* carries a `.name`. It used to resolve to the synthetic `{"type":"commonjs"}`
* marker MSD wrote at the config root, so post-install the worker queried
* `npm view undefined version` → latest stayed null → update_available
* permanently false; since #2544 MSD writes no marker there at all, so the
* require would now fail to resolve outright. The old structural test passed
* only because it grepped the DEV tree, where package.json still has a name.
*
* New contract (#498): the worker no longer resolves the package name itself.
* It delegates the latest-version lookup to check-latest-version.cjs's
* `checkLatestVersion()`, whose `PACKAGE_NAME` is sourced from the baked Package
* Identity seam (`msd-core/bin/lib/package-identity.cjs`). The seam's value
* is a build-time constant, correct in every install layout, so the
* undefined-at-runtime failure cannot recur. This test locks that contract:
*
* 1. Structural: worker must NOT contain the bare unscoped literal.
* 2. Structural: worker must NOT use `require(...package.json...).name`
* (the runtime-broken path).
* 3. Structural: worker delegates to check-latest-version's
* `checkLatestVersion` rather than calling `npm view` itself.
* 4. Single-source: check-latest-version's PACKAGE_NAME === the seam's
* packageName === the scoped '@golem15/msd-core'.
*
* Source-grep policy: this test reads hook source via readFileSync. Since
* #3545 lint-no-source-grep also covers hooks/, not just bin/lib/msd-core.
* The behavior (correct name → no E404) only manifests at runtime
* against the live registry; structural assertions are the minimum-cost
* contract for the worker, the same rationale #378 carried. See the
* site-scoped `allow-test-rule` marker directly above the readFileSync()
* call in workerCodeOnly() below.
