Fix: Prevent matching package names starting with 'uv' in dependency parsing

[phpmypython]

Summary

This PR fixes a bug introduced in #486 where packages starting with 'uv' (like 'uvicorn', 'uvloop') were incorrectly being parsed as uv version specifications.

The Problem

The current code uses dep.startsWith("uv") which matches any package name starting with 'uv', not just the 'uv' package itself. This causes:

• uvicorn==0.35.0 to be parsed as icorn==0.35.0
• uvloop==0.19.0 to be parsed as loop==0.19.0
• Any other package starting with 'uv' to be incorrectly interpreted

The Solution

Changed the matching logic to only match dependencies that start with 'uv' followed immediately by a version specifier character (=, <, >, ~, \!):

// Before
.find((dep: string) => dep.startsWith("uv"))

// After  
.find((dep: string) => dep.match(/^uv[=<>~\!]/))

This ensures we only match actual 'uv' package specifications like:

• ✅ uv==0.35.0
• ✅ uv>=0.35.0
• ✅ uv~=0.35.0

And correctly ignores other packages:

• ❌ uvicorn==0.35.0
• ❌ uvloop==0.19.0
• ❌ uv-tool==1.0.0

Testing

The existing test with uv==0.6.17 continues to work correctly. This fix prevents false positives from other packages.

Fixes the issue reported where GitHub Actions were failing with:

Found version for uv in /path/to/pyproject.toml: icorn==0.35.0
No version found for icorn==0.35.0

Fixes: #489
