Implement wildcard version matching for pip solver (==X.*)

[Copilot]

The pip solver rejected requirements like httpcore==1.* despite matching versions being available on PyPI. This prevented installing packages like huggingface-hub that depend on wildcard version specs.

Changes

packages/mambajs/src/solverpip.ts

• Updated regex to accept asterisks in version strings: [\w.*]+
• Added wildcard matching logic for == operator:
  • Extracts prefix before .* (e.g., 1.* → 1)
  • Matches version components against prefix parts
  • Includes boundary checks for edge cases
  • Per PEP-440, only trailing wildcards are supported

unittests/tests/pip/test-process-requirement.ts

• Added tests for httpcore==1.* and certifi==2024.*

Example

// Before: Would throw "Could not find a version that satisfies..."
satisfies('1.0.5', '==1.*')  // ❌ false

// After: Correctly matches versions with prefix
satisfies('1.0.5', '==1.*')  // ✅ true
satisfies('1.2.3', '==1.*')  // ✅ true  
satisfies('2.0.0', '==1.*')  // ✅ false

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

<issue_title>httpcore version not satisfied</issue_title>
<issue_description>I try to use the huggingface-hub library which has as dependency httpcore. It's pure Python.
I get this error:

Comments on the Issue (you are @copilot in this section)

@martinRenou Thanks for opening an issue @Alex-PLACET !

It's about implementing support for the requirement notation httpcore==1.* in the pip solver.

Let's see if the AI is up to a first look at it. We should follow as closely as possible the logic that real pip would take.</comment_new>

Looks alright to me. Even ran linters!
