fix(cli): bound docs parity process starts

[senthilr-nv]

Summary

The compiled CLI documentation contract started one Node.js process for every documented command. Under parallel package-contract load, those cold starts reached the existing 120-second subprocess limit. The check now reads compiled oclif flag metadata once and retains rendered-help checks for commands that provide custom help.

CI root cause: docs CLI parity / flag comparison / one cold compiled CLI start per documented command
Source run: https://github.com/NVIDIA/NemoClaw/actions/runs/32315705454 (run 32315705454, attempt 1)
Source main commit: 4fa8f85a634cf9dcfae2a57f44829fdbcfa43599 (GitHub Verified)
Failed job: build-typecheck (https://github.com/NVIDIA/NemoClaw/actions/runs/32315705454/job/96267789922)
Signature: Error: spawnSync bash ETIMEDOUT after 120112 ms
Scope: one root cause

Changes

• Add an internal compiled CLI flag dump sourced from the oclif metadata used by ordinary command help.
• Use that dump for ordinary flag parity and keep rendered-help checks for custom-help commands.
• Record the exact compiled CLI process set in the package contract. The check now starts 15 processes instead of 85 without changing the timeout or documentation assertions.

📝 Walkthrough

Walkthrough

The CLI now exposes canonical command-flag metadata through --dump-command-flags. Documentation parity checks consume this metadata and use rendered-help fallback for custom-help commands. Contract tests verify parity diagnostics and invocation behavior.

Changes

Command Flag Parity

Layer / File(s)	Summary
CLI metadata route src/lib/cli/argv-normalizer.ts, src/lib/cli/argv-normalizer.test.ts, src/lib/cli/command-registry.ts, src/lib/cli/public-dispatch.ts	The CLI recognizes --dump-command-flags, emits canonical command flag lines with help-source information, and skips legacy state migration for state-free metadata requests.
Custom-help metadata src/lib/cli/oclif-metadata.ts, src/lib/cli/generate-oclif-metadata-manifest.ts, src/commands/sandbox/*, src/commands/uninstall.ts	Command metadata supports customHelp. Selected sandbox and uninstall commands declare custom-rendered help, and manifest generation preserves the property.
Documentation parity discovery test/e2e/e2e-cloud-experimental/check-docs.sh, test/package-contract/cli/public-cli-contracts.test.ts	The checker selects compiled metadata or rendered help for flag comparison. Contract tests cover parity output, invocation logging, and undocumented custom-help flags.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to a87cf

The PR reduces compiled CLI starts for docs parity, but the check still uses synchronous CLI invocations without per-process timeout and termination handling; a stalled command could hang the E2E job, so merge should wait for this bounded-process behavior to be fixed or explicitly accepted.

84-101: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Prefer stable behavioral assertions over a full invocation snapshot.

The exact ordered invocation list couples this test to internal subprocess order and unrelated calls. A valid implementation can preserve flag parity and custom-help fallback behavior while changing harmless ordering, then fail this test. Assert the parity result, required dump and fallback behavior, and a stable process-count bound instead of the complete mock-call sequence.

As per path instructions, tests should favor observable behavior over implementation-specific mock-call assertions.
