Migrate CLI E2E tests to Node.js 26

Run the CLI subprocess suites and benchmark tools as native TypeScript with
node:test, and move them under test/e2e-cli.

Update CI and Compose runners, run local smoke tests on Linux, macOS, and
Windows, and collect source-mapped CLI coverage with c8.

+/**
+ * Node.js port of test-remote-commands-linux.sh
+ *
+ * Tests remote management commands: remote-status, lock-remote, unlock-remote,
+ * and mark-resolved.
+ *
+ * Scenario:
+ *   1. Start CouchDB, create a test database, and perform an initial sync.
+ *   2. Run remote-status and assert that the output contains the database name in JSON format.
+ *   3. Run lock-remote and verify that the remote database is locked.
+ *   4. Lock the remote database milestone manually, verify status, and run unlock-remote.
+ *      Assert that the output of unlock-remote contains the unlocked verification status.
+ *   5. Lock the remote database milestone manually, run mark-resolved, and verify that the
+ *      current device is accepted.
+ *
+ * Run:
+ *   node --test test-remote-commands.ts
