- Organize by "About" -> "Contributing" -> "Editing" -> "Maintaining" rather than mixing sections - Deduplicate a few lines into the guide itself - Recommend `mdbook serve` over `mdbook build` - Document `mdbook` layout and link to the upstream docs - Document sembr and that relative links must use `.md` extensions - Add a section on testing the tools in `ci/`
Fix some typos
Make README more complete and easier to follow
Dedup a bunch of information that's already on Forge

That is not all it does
fix "all x does is call ./x"
Installing cargo tools (`cargo install`) without locked dependencies exposes users to supply-chain attacks to all the dependencies of the tool (https://blog.rust-lang.org/2026/08/20/supply-chain-attack-on-arrayref/). Using `cargo install --locked` reduces this risk to a compromise of the tool itself, while using the locked and hashed version of the dependencies. I went through all `rg "cargo install"` hits in the repository and added `--locked` to all but explanatory examples (such as cargo's docs on `cargo install` itself). I validated that those tools publish functioning `Cargo.lock`s with https://gist.github.com/konstin/bcb1169c1c1120c259dca64e777a64d0.
- remove discouraging "pretty simple" in a complex chapter - mention that queries are demand-driven, not just memoized - emphasize that "query system" is a term of art (c.f. "Improper Nouns": https://siderea.dreamwidth.org/1773806.html)
