ACP doesn't seem to recognize command line options

[utsahi]

Describe the bug

E.g.,

1. --excluded-tools=grep,glob,web_fetch in interactive mode prints Disabled tools: glob, grep, web_fetch on console. But in ACP mode, prompting the LLM to print the available tools will still show the excluded tools.
2. --reasoning-effort=high works in interactive mode (confirmed from console + logs show "model": "capi:gpt-5-mini:defaultReasoningEffort=high") but not in ACP mode.

Affected version

GitHub Copilot CLI 1.0.5

Steps to reproduce the behavior

1. Run in acp mode with the command line options above
2. Initialize the session
3. Send a prompt
4. Inspect the logs (--log-level=all works in ACP mode)

Expected behavior

No response

Additional context

Fedora 43 x64.
