[Bug]: Local ACP provider fails to initialize Hermes via Ollama (60s timeout) despite working in CLI #33104

Before submitting#

• I searched existing issues and did not find a duplicate.
• I included enough detail to reproduce or investigate the problem.

Area#

apps/desktop

Steps to reproduce#

1. Configure a Local ACP provider in the UI
2. ACP source: Local command
3. Executable: hermes (or absolute path to hermes.exe)
4. Arguments: acp
5. Save and trigger the provider refresh/session creation.
6. Observe the startup attempt.

Expected behavior#

The ACP agent should successfully resolve, establish communication over standard input/output, and create a test session within the startup window.

Actual behavior#

The initialization hangs, and after 60 seconds, the UI outputs the following error state: "Status: Needs attention The ACP agent did not resolve and create a test session within 60 seconds. Package installation or agent startup may be slow; this check retries on the next provider refresh."

Impact#

Major degradation or frequent failure
