chore: Migrate from Poetry to uv and Hatchling

[dividedmind]

This commit migrates the project's dependency management and build system from Poetry to uv and Hatchling.

This change significantly speeds up dependency installation and testing, providing a more efficient development workflow.

Key changes include:

• pyproject.toml is now configured for Hatchling and uv.
• GitHub Actions workflows have been updated to use astral-sh/setup-uv.
• tox.ini is reconfigured to use tox-uv for test environments.
• README.md has been updated with new setup and usage instructions.
• Obsolete Poetry and pyenv files (tool-versions.example, etc.) have been removed.

ci/scripts/build_with_uv.sh:8

• Using $* here will perform word-splitting and can corrupt arguments that contain spaces (and it also drops original argument boundaries). Prefer passing through arguments as "$@" so flags/values are forwarded safely.
  ci/scripts/build_with_uv.sh:17
• Same argument-forwarding issue here: $* can break when any argument contains whitespace. Use "$@" to forward the original argument list safely.

ci/scripts/build_with_uv.sh:8

• uv build $* will perform word-splitting and glob expansion, which can corrupt arguments (e.g., paths with spaces) and changes behavior vs. the caller’s intent. Use "$@" when forwarding command arguments (both here and the non-exec invocation below).
  ci/scripts/build_with_uv.sh:16
• This second uv build $* has the same argument-forwarding problem as the earlier exec line; $* will split/expand unexpectedly. Use "$@" when passing through arguments.
