Replace hand rolled CLI tooling

[SorraTheOrc]

The current CLI is using a hand-rolled management suite. Replace it with a maintained CLI framework that provides subcommands, unified help, parsing, completion, extensibility, and improved developer DX.\n\nUser stories:\n- As a contributor, I can run with consistent subcommands and help.\n- As a user, default install exposes / commands via package.json scripts and bin entries.\n\nAcceptance criteria:\n- Replace hand-rolled argument parsing in with a standard CLI framework (candidate libs: oclif, yargs, commander).\n- Preserve existing commands and behavior (generate, start, etc.) and ensure tests pass ().\n- Update , scripts, and docs/README examples.\n- Add integration tests for new CLI entrypoints and update any snapshot/helpers.\n\nAffected files (initial): , , , tests under .\n\nSuggested next step: break this into child work items for evaluation, implementation, tests, and docs.

\n\n**OpenCode**\n\nPlan: changelog\n- Created feature work items:\n - TF-0MMJ892CE0Y4MFFL: Framework migration: core parser\n - TF-0MMJ894WA1IHEKV9: Preserve CLI UX: help and machine output\n - TF-0MMJ897F20HTCQHE: Developer DX & install ergonomics\n - TF-0MMJ899TT0RPVHEG: Tests & integration coverage for CLI\n - TF-0MMJ89CGG1W2LXI9: Docs, demos and rollout plan\n- Reused existing child task: TF-0MMJ7YHID0S9PFY1 (Evaluate CLI libraries; in_progress)\n- Dependencies added between features to enforce sequencing (framework -> UX/tests/docs)\n- Planning defaults applied for now (can change after evaluation):\n - Preferred CLI lib: Commander (default; final decision by TF-0MMJ7YHID0S9PFY1)\n - Migration style: Incremental\n - Output compatibility: Preserve exact textual output for compatibility\n- Open Questions:\n 1) Confirm final CLI library choice after evaluation completes.\n 2) Confirm whether to preserve exact textual output for snapshot-heavy tests or allow opt-in formatting changes.

\n\n**OpenCode**\n\nImplementation started: added and updated to use the commander wrapper. Claimed Framework migration feature (TF-0MMJ892CE0Y4MFFL) and created follow-up tasks for UX, tests, install ergonomics, and docs. Next: implement minimal generate wiring inside commander wrapper and run tests.

\n\n**OpenCode**\n\nUpdated plan: CLI library set to yargs per docs/cli-library-evaluation.md; replaced commander wrapper with yargs wrapper (src/cli.yargs.ts). Proceeding with incremental migration per plan. Open Questions: verify if we should add yargs to dependencies now or in the first implementation PR.

\n\n**OpenCode**\n\nImplementation update: added to and switched dev loader to . Proceeding to implement POC command module under and will add compatibility shim if needed. Next: create POC command, wire to existing renderRecipe/encodeWav path, run tests.
