Semgrep diagnostic reports disabled even when semgrep is installed via uv

[danieldekay]

Problem

The Semgrep pattern diagnostic reports:

• Semgrep Pattern ⊘ Disabled Semgrep CLI not installed (install: pip install semgrep)

This happens even though the project has Semgrep installed and available in the uv environment.

Reproduction

1. In the TangoAtlas workspace, install Semgrep with uv add semgrep.
2. Run uv run semgrep --version.
3. Run the diagnostic that prints the Semgrep Pattern status.

Observed behavior

• uv run semgrep --version succeeds.
• The shell can also resolve semgrep.
• The diagnostic still says Semgrep is not installed and marks the pattern disabled.

Expected behavior

• If Semgrep is available in the active project environment, the diagnostic should report it as enabled.
• The diagnostic should not tell the user to install Semgrep with pip install semgrep when Semgrep is already present via uv.

Notes

The issue appears to be an environment detection mismatch rather than a missing dependency declaration.
