Zoltan KochanandClaude Opus 5.5 6f95957063 docs: lint prose with Vale (#17238)
* docs: lint prose with Vale

Add Vale with an in-repo style, .vale/styles/pnpm, that turns the
writing rules in AGENTS.md and the Google developer documentation style
guide into lint rules. The stock Vale packages (Google, Microsoft,
RedHat, write-good) were too noisy to block on, for example 1,300
passive-voice hits in the v12 docs alone, so the rules are written for
this repo, following the GitLab model. Each one links the guideline it
enforces.

Levels:
- error, fails CI: dashes, plain-word substitutions, condescending
  words, "please", "note that", hedges, puffery, optional plurals,
  exclamation marks, ellipses, curly quotes, generic link text, product
  spellings, sentence-case headings, repeated words, double spaces,
  implementation history in comments; in changesets, bold or italic
  emphasis, internal names and release-line names.
- warning: future tense, sentences over 30 words, "instead of" and
  "so that" tails in changesets.
- suggestion: passive voice.

.vale.ini scopes the rules. Docs get every rule. Contributor Markdown
and code comments keep dashes and headings as warnings until their
roughly 8,100 em dashes are rewritten. Released changesets stay in
.changeset/ and are not rewritten, so lint-prose.mjs lints only the
changesets added since PROSE_BASE (the PR base in CI).

The prose workflow installs a pinned, checksum-verified Vale release and
runs `pnpm lint:prose`. The rest of this change rewrites the existing
docs, READMEs, contributor Markdown, and code comments to pass the
error-level rules. Only prose and comment text changed. Renamed
headings keep their anchors.

Spelling stays with cspell, which checks identifiers that Vale does not
see.

aliases Aliases

Aliases let you install packages with custom names.

Let's assume you use lodash all over your project. There is a bug in lodash that breaks your project. You have a fix but lodash won't merge it. Normally you would either install lodash from your fork directly (as a git-hosted dependency) or publish it with a different name. If you use the second solution you have to replace all the requires in your project with the new dependency name (require('lodash') => require('awesome-lodash')). With aliases, you have a third option.

Publish a new package called awesome-lodash and install it using lodash as its alias:

pnpm add lodash@npm:awesome-lodash

No changes in code are needed. All the requires of lodash will now resolve to awesome-lodash.

Sometimes you'll want to use two different versions of a package in your project. Easy:

pnpm add lodash1@npm:lodash@1
pnpm add lodash2@npm:lodash@2

Now you can require the first version of lodash via require('lodash1') and the second via require('lodash2').

This gets even more useful when combined with hooks. Maybe you want to replace lodash with awesome-lodash in all the packages in node_modules. You can easily achieve that with the following .pnpmfile.mjs:

function readPackage(pkg) {
  if (pkg.dependencies && pkg.dependencies.lodash) {
    pkg.dependencies.lodash = 'npm:awesome-lodash@^1.0.0'
  }
  return pkg
}

export const hooks = {
  readPackage
}
