The compiled gsd-core/bin/lib/*.cjs modules are gitignored build artifacts
(ADR-457) shipped prebuilt in the npm tarball. A Claude Code plugin-marketplace
/ git-clone install materializes the repo tree directly and never runs
`npm run build:lib`, so those ~148 files are absent and every CLI command dies
at load with `Cannot find module './lib/cli-exit.cjs'`.
gsd-tools.cjs now calls ensureRuntimeBuild() before its ./lib requires: a new
committed bin helper that compiles the tree once on demand (lock-guarded,
incremental-cache-cleared, portable `node <tsc>` invocation) when the sentinel
cli-exit.cjs is missing, and surfaces an actionable error when TypeScript is
unavailable. The already-built npm path is a single fs.existsSync no-op.
ADR-457 (gitignored, build-at-publish) is preserved; no release-pipeline change.
Verified against a simulated marketplace checkout (148 build outputs removed):
the CLI self-heals and the result is byte-identical to `npm run build:lib`.
Closes#2002
