What does this PR do?

LocalEnvironment._run_bash() spawns subprocess.Popen() without a cwd argument. This causes init_session() — which runs pwd -P to capture the initial working directory — to execute in the gateway process's startup directory instead of the user-configured terminal.cwd. The result is then written back to self.cwd, silently overwriting the correct path.

This PR adds cwd=self.cwd to the subprocess.Popen() call so the initial session snapshot correctly captures the working directory from config.yaml's terminal.cwd setting.

Related Issue

No existing issue filed, but this bug is reproducible by:

1. Setting terminal.cwd: /some/absolute/path in config.yaml
2. Starting Hermes (gateway starts from a different directory, e.g. ~/.hermes/hermes-agent)
3. Running pwd via the terminal tool — it returns the gateway directory, not the configured one

Type of Change

• 🐛 Bug fix (non-breaking change that fixes an issue)

Changes Made

• tools/environments/local.py: Add cwd=self.cwd to subprocess.Popen() in _run_bash() (line 268)

How to Test

Reproduce the bug (before this fix):

1. In config.yaml, set:

   terminal:
     cwd: /tmp/test-workspace

2. Start Hermes from a different directory (e.g. ~/.hermes/hermes-agent)
3. Run pwd — observe it returns ~/.hermes/hermes-agent instead of /tmp/test-workspace

Verify the fix (after this PR):

1. Apply the change
2. Start Hermes from any directory
3. Run pwd — it now correctly returns /tmp/test-workspace
