[Czaki]

Add an option to easily reproduce the problem locally using tox.

Closes #1451

Summary by Sourcery

Provide a tox workflow to reproduce and validate the problematic PyInstaller dependency environment.

Enhancements:

• Add a dedicated tox environment for reproducing problematic pre-release dependency resolutions in the PyInstaller build.

Build:

• Remove the problematic-version requirement constraints used during pre-test setup.

Tests:

• Add automated build and smoke-test coverage for the PyInstaller executable under the problematic dependency environment.

Summary by CodeRabbit

• Bug Fixes

  • Updated dependency compatibility rules to support additional prerelease versions.

• Tests

  • Added validation for building and running the packaged application with prerelease-compatible dependencies.

• Chores

  • Improved automated environment setup for testing executable builds.

Reviewer's Guide

The PR removes restrictive mpmath constraints and adds a pyinstaller-pre tox environment that reproduces the pre-release dependency resolution, packages the application, and runs the packaged executable's self-test to verify the environment.

<issue_to_address>
**issue (bug_risk):** tox rejects the first `uv pip compile` command as an unallowlisted external command, so `pyinstaller-pre` stops before compiling or installing its requirements.

**Triggers:** When running `tox run -e pyinstaller-pre` under tox 4.

**Suggested fix:** Add `uv` to `allowlist_externals` and ensure the uv executable is installed or otherwise available on PATH.

```suggestion
allowlist_externals =
    dist/PartSeg/PartSeg
    uv
deps =
    uv
commands_pre =
```
