gsxdsm b563b12662 feat: add Oh My Pi (omp) ACP runtime plugin (#2083)
## Summary

- Add `fusion-plugin-omp-runtime` so Fusion agents can run through
operator-installed **Oh My Pi (`omp`)** over the [Agent Client
Protocol](https://omp.sh/docs/acp) (`omp acp`).
- Wire staged/bundled install, Settings → Authentication card (enable +
binary path), model discovery (`omp models` → `omp-cli/*`), and MCP
eligibility for runtime id `omp`.
- Forward Fusion `systemPrompt` via ACP `session/new`
`_meta.systemPromptOverride`.

## How operators use it

1. Install/auth `omp` (credentials under `~/.omp`).
2. Enable **Oh My Pi — via omp ACP** in Settings → Authentication
(optional binary path).
3. Set agent **Runtime Source → OMP Runtime** (`runtimeHint: "omp"`), or
pick an `omp-cli/*` model when enabled.

## Known v1 gaps

- No Grok-style Fusion `fn_*` loopback tool bridge yet (operator MCP is
forwarded; in-process custom tools are not).
- Model is fixed at spawn (`omp --model … acp`); no mid-session Fusion
model switch.

## Test plan

- [x] `pnpm --filter @fusion-plugin-examples/omp-runtime test` (unit +
live ACP when `omp` is on PATH)
- [x] Auth routes: `POST /api/auth/omp-cli`, `GET
/api/providers/omp-cli/status`
- [x] Engine `runtimeSupportsMcp("omp")`
- [ ] Manual: enable card in dashboard, select OMP runtime on an agent,
run a short chat turn

## Summary by CodeRabbit

* **New Features**
* Added Oh My Pi (OMP) CLI support as an ACP-backed runtime and model
provider, including model discovery and probing.
* Added dashboard auth/status controls to enable OMP, check readiness,
and configure the local binary path (with validation).
* Exposed OMP custom `fn_*` tools via an MCP loopback bridge, plus
optional filesystem capabilities and stricter tool permission gating.
* **Documentation**
* Added/expanded OMP runtime contract and integration docs (including
the ACP session/handshake flow).
* **Tests**
* Added Vitest coverage for settings wiring, provider status, model
discovery, runtime sessions, permissions, MCP bridging, and live
connectivity.

* `image` blocks (passthrough — KTD ContentBlock image variant).
