chore(treefmt): replace prettier with oxfmt and simplify CI (#73)

* build(treefmt): replace prettier with oxfmt

Migrate from prettier to oxfmt for formatting non-Python files.
oxfmt is part of the oxc project and provides faster formatting
with native Rust implementation.

Changes:
- Remove prettier configuration from treefmt programs
- Add oxfmt as custom formatter with explicit includes
- Extend supported file types: md, yml, yaml, json, ts, tsx, js, jsx, html, css
- Update flake.lock with latest nixpkgs containing oxfmt

* chore(just): consolidate lint and format commands

Simplify justfile by combining related operations:
- lint: now includes format check (nix fmt --fail-on-change)
- format: replaces lint-fix, runs ruff fix and nix fmt together

This makes the CI workflow simpler as format checking is now
part of the lint command.

* refactor(ci): simplify lint by leveraging treefmt

treefmt already includes ruff-check and typos, so remove redundant
commands from justfile and CI workflow.

Changes:
- Remove separate `uv run ruff check` from lint (treefmt runs ruff-check)
- Remove `typos` and `typos-fix` commands (treefmt runs typos)
- Remove typos CI job (covered by lint via treefmt)
