Implement UV for dependency lock - #956
Conversation
Pandas 2 got rid of the `Int64Index` class, it was downcasting to int32 for the input land use table
Consider removing unused ones at a later time
This dependency was replaced with “state” for workflow orchestration.

Pull Request Overview
This PR introduces UV as the new package and project manager for ActivitySim by updating dependency constraints in pyproject.toml, replacing several conda environment YAML files, and adjusting related test and release workflows. Key changes include:
- Updating pyproject.toml to include dependency groups and a [tool.uv] section with stricter version constraints.
- Removing conda environment files in favor of managing dependencies with UV.
- Modifying code and GitHub Actions workflows to use uv-based commands (e.g. uv sync, uv run) and ensuring compatibility with Windows.

- Verify that all related developer and user documentation is updated to reflect the switch from conda to uv for dependency management.

- Ensure that all workflow commands are compatible with PowerShell syntax, as switching from bash may lead to issues with commands originally written for bash.

Add a note here to remind users: if they already have uv installed from older projects and they they encounter errors later in the process, that they may need to update uv via uv self update or by using whichever package management tool is managing the uv tool. (e.g., I got "error: Failed to parse uv.lock ... missing field version" on my first attempt, which was resolved by updating uv)

Cool! Added the note. Thank you.

This PR implements UV as the new package and project manager for ActivitySim. #954
Changes to package and project management
uv.lockfor complete dependencies [1][2]Updates to GitHub Actions tests
Updates to documentation
Other Fixes
Int64Indexdtype, which caused some existing tests to fail on Windows due to index type mismatch. We updated key state data tables' index type to ensure they areint64across platforms and pandas versions. [1][2]Update: This also solves Issue #958. Apparently index type
int32has caused bigger issues in full model runs that were not observed in our GitHub Actions tests. Our fix should address that too. See my response in: #958 (comment)Consideration for future improvements
orca, were still included in those yaml files. We removed some but definitely not all. It requires careful auditing and testing to remove all, which is out of scope for now.@josiekre
