Sanity Checking

• I have read and understood the contribution guidelines
• I have updated the changelog as per my changes
• I have tested, and self-reviewed my code
• Style and consistency
  • I ran nix fmt to format my Nix code
  • I ran cargo fmt to format my Rust code
  • I have added appropriate documentation to new code
  • My changes are consistent with the rest of the codebase
• Correctness
  • I ran cargo clippy and fixed any new linter warnings.
• If new changes are particularly complex:
  • My code includes comments in particularly complex areas to explain the
    logic
  • I have documented the motive for those changes in the PR body or commit
    description.
• Tested on platform(s):
  • x86_64-linux
  • aarch64-linux
  • x86_64-darwin

📝 Walkthrough

Walkthrough

Adds deno and taplo as project formatters: flake.nix extends its formatter wrapper to run taplo fmt for TOML and deno fmt for Markdown, shell.nix adds deno to nativeBuildInputs, and Justfile gains deno-check/deno-fmt recipes wired into the existing check and fix targets. The remaining file changes are formatting-only normalizations across CHANGELOG.md, docs/README.md, .github/ISSUE_TEMPLATE/bug.yml, and .github/workflows/.

Changes

Deno/TOML Formatter Integration and Applied Cleanups

Layer / File(s)	Summary
Deno/TOML formatter wiring in flake, shell, and Justfile flake.nix, shell.nix, Justfile	flake.nix extends the formatter wrapper to invoke taplo fmt for TOML files and deno fmt for Markdown, adding both tools to runtimeInputs. shell.nix adds deno to nativeBuildInputs. Justfile adds deno-check (deno fmt --check) and deno-fmt (deno fmt .) recipes and includes them in the check and fix dependency lists.
Formatting normalization across docs and config CHANGELOG.md, docs/README.md, .github/ISSUE_TEMPLATE/bug.yml, .github/workflows/changelog.yaml, .github/workflows/cleanup.yaml	Line-wrapping, indentation, and quote-style normalization applied with no semantic changes: CHANGELOG entries reflowed, README nh search table and NH_FILE/NH_ATTRP paragraph rewrapped, bug template YAML whitespace and indentation adjusted, cleanup workflow date value re-quoted with double quotes, and changelog workflow trailing blank line removed.

I'm not a big fan of using a js runtime for formatting, but as discussed with @NotAShelf, there are no other good Markdown formatters we're both happy with.

Verify each finding against current code. Fix only still-valid issues, skip the
rest with a brief reason, keep changes minimal, and validate.

Inline comments:
In `@flake.nix`:
- Around line 58-59: The comment states "Format Nix with Alejandra" but the
actual command on the following line invokes nixfmt, which is a different
formatter. Update the comment to accurately reflect the tool being used in the
fd command. Change the comment to state "Format Nix with nixfmt" to match the
nixfmt command that is actually being executed.
- Around line 64-65: The Markdown formatter in flake.nix excludes docs/API.md
using the `-E docs/API.md` flag in the fd command, but this file does not exist
in the repository and the Justfile's deno-fmt recipe does not apply this same
exclusion. Remove the `-E docs/API.md` exclusion from the fd command unless this
file is planned to be generated or managed externally, in which case add a
comment explaining the purpose of the exclusion.

In `@Justfile`:
- Line 4: Update CONTRIBUTING.md at lines 91-100 to document the Deno formatting
step that is now included in the check and fix tasks. The `check` recipe in
Justfile includes `deno-check` and the `fix` recipe includes `deno-fmt`, but the
current documentation only lists cargo-based tools. Add documentation for the
`deno fmt` step to the task descriptions so users are aware that Deno formatting
checks are part of the check and fix process.
