Replace stylua pre-commit hook with prebuilt-binary install

[laurigates]

Problem

The stylua pre-commit hook in .pre-commit-config.yaml is the upstream JohnnyMorganz/StyLua hook, which installs stylua via cargo install from source. This requires a working Rust toolchain including a system C linker (cc).

On hosts without cc (notably TrueNAS appliances where apt is disabled), the hook env install fails with:

error: linker `cc` not found
error: could not compile `proc-macro-error-attr` (build script) due to 1 previous error
…
error: failed to compile `stylua v2.1.0`

This blocks every commit from such hosts, even commits that don't touch any Lua files (pre-commit installs hook envs eagerly on first use).

Workaround in use: SKIP=stylua git commit … per commit.

Why

The dotfiles repo only has a few Lua files (Neovim config). It's not worth requiring a full Rust + C toolchain on every machine that wants to commit changes — especially on minimal Linux hosts where the user can't apt install build-essential.

What

Swap the stylua pre-commit hook to a variant that uses a prebuilt binary instead of building from source. Two viable options:

1. pre-commit-stylua (JohnnyMorganz/StyLua#stylua-prebuilt ships an alternative hook id) — the official prebuilt-binary hook, downloads a release asset.
2. Local hook invoking stylua from \$PATH, with stylua installed via mise/aqua/brew on each platform.

Option 1 keeps the workflow uniform across machines without per-host install. Option 2 reuses the mise-managed binary if we add it.

How

Edit .pre-commit-config.yaml:

# Before
- repo: https://github.com/JohnnyMorganz/StyLua
  rev: v2.1.0
  hooks:
    - id: stylua

# After (option 1 — prebuilt)
- repo: https://github.com/JohnnyMorganz/StyLua
  rev: v2.1.0
  hooks:
    - id: stylua-system  # or stylua-prebuilt — verify exact id from upstream

Verify by:

• Removing the existing pre-commit hook env (pre-commit clean or rm -rf ~/.cache/pre-commit/repo*)
• Running pre-commit run stylua --all-files on TrueNAS with no cc available — it should succeed.
• Running on macOS to confirm parity.
