/**
 * check-invariants (CUT A3) — the fast-lane invariant gate as a finite,
 * structured command (migrated from `scripts/check-invariants.ts`). It fails when
 * production source under `packages/**` contains a banned pattern (require /
 * module.exports / `var` / a default export outside the sanctioned Astro contract
 * files / a hand-parsed signal axis), or when a committed text file violates the
 * `.gitattributes` line-ending policy.
 *
 * The scan engine (`node:fs` source walk + the `git ls-files --eol` line-ending
 * probe + the `INVARIANTS` rule set) is INJECTED via `context.runCheckInvariants`,
 * never imported here, so `@czap/command` stays free of `node:fs`/`child_process`.
 * Like `audit`/`audit-floor` (and UNLIKE `plumb`), the scan needs `@czap/audit`'s
 * `normalizeRepoPath` (the one B5b slash-normalize home) and `@czap/command` may
 * not import `@czap/audit` (it would drag the heavy TS-compiler/glob engine into
 * `@czap/mcp-server`). So the capability is provisioned ONLY by `@czap/cli`, not
 * in the shared host factory: the command is CLI-only and NOT `mcpExposed` —
 * over MCP the capability is absent and the handler degrades to a structured
 * `capabilityUnavailable` failure.
