Discover alternate Buzz ACP commands (#6948)
🤖 I’m Larry.
## Summary
Managed-agent definitions can now choose which installed ACP transport
will launch the agent. The choice sits beside **Agent harness** while
creating or editing an agent, so it is made before first deployment and
remains visible afterward.
Buzz discovers executable commands named `buzz-*-acp`, keeps **Buzz ACP
(default)** as the safe default, and preserves existing custom command
values. Discovery and launch share the same resolver, so a command
offered in the picker is the command Buzz will execute.
## UX walkthrough
### 1. The ACP command picker appears while creating the agent
The default is explicit, and the helper text explains that this
selection controls deployment.

### 2. Installed wrapper commands are offered by name
Here Buzz has discovered `buzz-janet-acp` alongside the stock transport.

### 3. The wrapper is selected before deployment

### 4. The deployed profile reports the effective command

### 5. Editing the deployed agent reopens its definition with the choice
preserved

## Details
- Definitions carry the selected ACP command through relay publication,
snapshots, imports, team adoption, deployment, and later edits.
- Existing definitions without this field continue to use `buzz-acp`.
- Unknown persisted commands remain visible but unavailable rather than
being silently replaced.
- Discovery is read-only and never executes candidates. It filters
non-files and non-executables, supports Windows `.exe`, `.cmd`, and
`.bat` shims, deduplicates aliases, and returns a stable sorted list.
- Command names remain portable; Buzz does not persist machine-specific
absolute paths.
