fix(detect): recognize versioned Python agent wrappers

[plarson]

Summary

• recognize versioned Python runtime names such as python3.12
• inspect the wrapped script path so Nix-installed Hermes processes are identified
• add a regression test matching the observed python3.12 .../bin/hermes process shape

Verification

• regression test fails on unmodified master with None instead of Hermes
• regression test passes with this patch
• detection tests: 47 passed
• just lint: passed
• just ci was run locally; three unrelated live-handoff/API integration tests failed and one was reproduced unchanged on origin/master in a clean worktree

No documentation change is needed; this restores existing Hermes detection behavior for versioned Python launchers.

📝 Walkthrough

Walkthrough

Python runtime detection now recognizes executables such as python3.12. Wrapped-agent detection uses this classification to identify Hermes launched through versioned Python wrappers. A regression test covers the python3.12 case.

Changes

Python runtime detection

Layer / File(s)	Summary
Recognize versioned Python runtimes src/detect/mod.rs	is_python_runtime recognizes python and numeric dotted Python executable suffixes.
Apply detection to wrapped agents src/detect/mod.rs	Wrapped-agent argument handling uses recognized versioned Python runtimes. A regression test covers Hermes launched through /nix/store/.../python3.12.

Greptile Summary

This PR restores agent detection for versioned Python launchers by recognizing numeric Python runtime suffixes and inspecting the wrapped script path.

• Adds shared recognition for names such as python3.12.
• Applies versioned-runtime recognition during generic-process classification and argv unwrapping.
• Adds a regression test for a Nix-installed Hermes process launched through python3.12.

Confidence Score: 5/5

The PR appears safe to merge.

No blocking failure remains.

Pull request overview

Improves agent-process detection so Hermes (and other wrapped agents) can be recognized when launched via versioned Python runtimes (e.g., python3.12), which is common with Nix-managed installs.

Changes:

• Extend generic runtime detection to treat python<version> (e.g., python3.12) as a Python runtime.
• Route versioned Python runtimes through the same “wrapped script name” parsing used for python/python3.
• Add a regression test covering the observed python3.12 .../bin/hermes process shape.
