Add mise.toml for tool version management

Use mise.toml as single source of truth for tool versions in both
local development and CI. This replaces manual version env vars and
installation scripts.

Changes:
- Add mise.toml with all tool versions
- Update CircleCI to install tools via mise
- Remove redundant manual installation scripts
- Simplify PATH configuration

Closes #1634
