build(test-error-sampler): Migrate to uv and pyproject.toml

[ericapisani]

Summary

• Replace pip/requirements.txt with uv/pyproject.toml for dependency management
• Update run.sh to use uv run instead of manual venv creation and pip install
• Remove legacy requirements.txt

Refs PY-2447

Test plan

• Verify pyproject.toml includes all dependencies from the original requirements.txt
• Verify run.sh uses uv run
• Verify requirements.txt is removed

Uv missing PATH after install

Medium Severity

When uv is not already installed, run.sh runs the Astral installer and then immediately invokes uv run. The installer only updates shell startup files for future sessions, so uv is often not on PATH in the current bash process and the script exits before main.py runs.

Bug: The requires-python constraint in pyproject.toml (>=3.12) conflicts with the version in .python-version (3.10.4), which will cause uv to fail.
_{Severity: HIGH}

Suggested Fix

Align the Python versions. Either update the .python-version file to a version that satisfies >=3.12 (e.g., 3.12), or adjust the requires-python constraint in pyproject.toml to be compatible with 3.10.4 (e.g., >=3.10.4).

Location: test-error-sampler/pyproject.toml#L4

Potential issue: The newly added `pyproject.toml` file specifies `requires-python =
">=3.12"`. However, the existing `.python-version` file in the same directory pins the
Python version to `3.10.4`. When `uv` is used to run the project, it prioritizes the
`.python-version` file for interpreter selection but then validates it against the
`requires-python` constraint. Since version `3.10.4` does not meet the `>=3.12`
requirement, `uv` will report an incompatibility error, causing the `run.sh` script to
fail.
