feat: multiple venv support, --active flag, auto pyproject sync, and terminal options

[ABCtoDev]

Summary

Add support for multiple virtual environment directory patterns with comprehensive venv management features.

Problem

Currently, uv.nvim only detects .venv directories. Many projects use different naming conventions like .venv-3.11, venv, or venv-dev.

Solution

Multiple venv pattern support

Added find_venvs() helper function that detects:

• .venv (exact match)
• .venv-* (prefix match, e.g., .venv-3.11, .venv-dev)
• venv (exact match)
• venv-* (prefix match, e.g., venv-py311)

Improved picker display

Updated both Snacks and Telescope pickers to show activation status:

• ● .venv (Active) - Currently active venv
• ○ .venv-3.11 - Available but inactive

venv-selector.nvim integration

Activating a venv through uv.nvim will also update venv-selector's state. This provides unified venv management across different picker UIs.

--active flag support for custom venv

When a non-default venv (e.g., .venv-3.11) is activated, uv commands automatically include the --active flag:

• uv add → uv add --active
• uv remove → uv remove --active
• uv sync → uv sync --active
• uv run → uv run --active

Auto pyproject.toml and .python-version sync

When switching to a different venv:

• Updates requires-python with strict range (e.g., >=3.11,<3.12)
• Updates .python-version file to match
• Runs uv lock with target Python version to resolve compatible packages
• Syncs packages and updates dependency versions in pyproject.toml

Auto LSP restart

After uv add/uv remove/uv sync commands complete, LSP is automatically restarted to recognize new packages immediately.

New execution options

execution = {
  -- Where to open the terminal: "split" | "vsplit" | "tab"
  terminal = "split",

  -- Hide result buffer from buffer list (tabline)
  hide_result_buffer = false,

  -- Reuse existing result split window instead of creating new one
  reuse_result_split_buffer = false,
}

Required Dependencies

• linux-cultist/venv-selector.nvim
• neovim/nvim-lspconfig
• nvim-telescope/telescope.nvim

Testing

• Tested with multiple venv patterns in workspace
• Verified Snacks picker displays correctly
• Confirmed venv-selector integration works
• Verified --active flag is added for custom venvs
• Confirmed LSP restart after package changes
• Tested terminal reuse and hide options

Breaking Changes

• venv-selector.nvim is now a required dependency
