Add Command Code (`commandcode`) as a supported AI provider

Command Code (https://commandcode.ai/) is not available as a provider in AgentsRoom, while the other CLIs I use are (Claude Code, Codex, Copilot, OpenCode).

Expected: Command Code selectable as a provider when creating an agent, with its models in the picker and its usage badge, like the other providers.

Actual: there is no Command Code entry. The only way today is routing its models through the OpenCode CLI with provider environment variables (CMDCC_API_KEY) and model ids such as commandcode/deepseek/deepseek-v4.1-flash: no provider entry, no model list, no quota badge.

Why it matters: I run most of my agents on Command Code models; a first-class provider would remove the manual per-machine setup. A comparable request of mine ("Add Devin as AI provider", 21 Aug) shipped, so I am filing this one the same way.

Note: I reported the same request on 27 September; that ticket does not appear on this board (its page returns 404), so please treat this one as the live report.

Problem to solve

Command Code cannot be selected as a provider in AgentsRoom, unlike Claude Code, Codex, Copilot or OpenCode. Today the only way is routing its models through the OpenCode CLI with provider environment variables (CMDCC_API_KEY) and model ids like commandcode/deepseek/deepseek-v4.1-flash: no provider entry, no model list, no usage/quota badge.

Proposed behavior

Add Command Code as a first-class provider: an entry next to the other CLIs when creating an agent, its models in the model picker, and the usual usage badge.

Who benefits

Users who already subscribe to Command Code and want to run AgentsRoom agents on it without per-machine environment setup.

Acceptance criteria

Agents can be launched on Command Code models exactly like on the other supported providers.
