chore(knip): ignore intentional root devDependencies

[blacksmith-sh]

Context

The 🧹 Unused code check CI job (pnpm exec knip) is failing on main. Knip reports four root devDependencies as unused:

Unused devDependencies (4)
@favware/npm-deprecate     package.json:28:6
@swc/core                  package.json:30:6
@types/ws                  package.json:32:6
cz-conventional-changelog  package.json:34:6

This failure is pre-existing on main (it was surfaced on the merged docs PR #3, which only touched README.md), so every PR and push currently trips the knip job.

Why these are intentional, not dead weight

None of these are actually removable; knip just can't see how they're used statically:

• @swc/core is an approved native build dependency in pnpm-workspace.yaml (allowBuilds), pulled in for the SWC-based tooling.
• cz-conventional-changelog is wired up through the commitizen config in package.json (config.commitizen.path).
• @favware/npm-deprecate is a release/maintenance CLI.
• @types/ws is part of the standard ecosystem type set.

The sister repo wolfstar-project/stars-components (which this monorepo is modeled after) already ignores this exact same set in its knip.json. This change mirrors that convention rather than deleting dependencies.

Change

Add the four dependencies to ignoreDependencies on the root workspace in knip.json:

".": {
  "project": ["*.ts"],
  "ignoreDependencies": [
    "@favware/npm-deprecate",
    "@swc/core",
    "@types/ws",
    "cz-conventional-changelog"
  ]
}

Verification

• pnpm exec knip now exits 0.
• pnpm exec oxfmt --check knip.json passes.
• pnpm exec changeset status --since=origin/main passes (root-only change, no package bump needed, so no changeset).

Confidence Score: 5/5

This looks safe to merge.

No blocking issues were found in the changed code. The ignore list is scoped to the root workspace, and package workspace checks remain configured separately.

No files need attention.
