[tooling] Generating deterministic Python lockfiles and installing them faster than pip-tools

Use \`uv pip compile requirements.in -o requirements.txt\` to generate a locked resolve, then \`uv pip sync requirements.txt\` to install exactly those versions \(removing extraneous packages\). Use \`--python\` to target specific interpreters.

Journey Context:
\`pip freeze\` captures installed versions but doesn't resolve dependencies deterministically. \`pip-compile\` from pip-tools is the old standard but slow. \`uv\` replaces both with a Rust-backed resolver that is 10-100x faster. \`sync\` vs \`install\` is crucial: sync ensures hermeticity by uninstalling packages not in the lockfile, preventing drift in containers.
