[BugFix] Fix Honcho HOME-aware config fallback

[HiddenPuppy]

Fixes #13283

Summary

• compute the shared ~/.honcho/config.json fallback from the current HOME at call time
• add regression coverage for HOME changes after import
• keep the existing Hermes-local and default-profile lookup order unchanged

Root Cause

GLOBAL_CONFIG_PATH captured Path.home() at import time, so later HOME overrides used by tests and isolated instances could still fall back to the original user's ~/.honcho/config.json.

Testing

• source venv/bin/activate && python -m pytest tests/honcho_plugin/test_client.py -q
• source venv/bin/activate && python -m pytest tests/hermes_cli/test_profiles.py -q
• source venv/bin/activate && python -m pytest tests/ -q (fails in unrelated ACP/approval/browser/media/vision areas and missing optional extras in this checkout)

[alt-glitch]

Likely duplicate of #13323 — same root cause (Honcho GLOBAL_CONFIG_PATH frozen at import time). Both fix #13283.

Thanks for the focused fix. This is an automated hermes-sweeper review: the PR's exact behavior and regression coverage are already on current main.
