chore: dead-code sweep — remove unused UI snippets and demo dependencies

[mbret]

Automated dead-code sweep. Candidates were surfaced with knip (temporary config, not committed) and every deletion was then verified by repo-wide greps (excluding node_modules, dist, coverage output) for the file basename, its import path, and each exported symbol — including intra-directory relative imports (./close-button style) and tsconfig path aliases. Only items whose searches came back empty were removed.

Deleted files (one line each, with evidence)

apps/demo (private app)

• src/components/ui/avatar.tsx — no import of ui/avatar anywhere in the workspace or repo
• src/components/ui/drawer.tsx — no import of ui/drawer in demo (the react-reader hit is that package's own, kept drawer.tsx)
• src/components/ui/input-group.tsx — no import of ui/input-group anywhere
• src/components/ui/popover.tsx — no import of ui/popover anywhere
• src/components/ui/tooltip.tsx — no import of ui/tooltip anywhere
• src/types.ts — declared only the __PROSE_READER_DEBUG global; nothing under apps/demo references that global (the packages that use it declare it themselves in packages/shared/src/report.ts)

packages/react-reader (published package — none of these are reachable from src/index.ts, so the published surface is unchanged)

• src/components/ui/accordion.tsx — no import of ui/accordion anywhere
• src/components/ui/avatar.tsx — no import of ui/avatar anywhere
• src/components/ui/checkbox.tsx — no import of ui/checkbox in react-reader (demo's checkbox usage is demo's own file)
• src/components/ui/input-group.tsx — no import of ui/input-group anywhere
• src/components/ui/popover.tsx — no import of ui/popover anywhere
• src/components/ui/tooltip.tsx — no import of ui/tooltip anywhere

Removed dependencies (apps/demo)

• @chakra-ui/styled-system — no source reference anywhere; npm ls shows demo as its only dependent (Chakra v3 no longer uses it)
• @react-rxjs/utils — no source reference anywhere; no other dependent
• react-use — no source reference anywhere; no other dependent
• stream-browserify — no source reference anywhere; demo's vite stream alias points at the local stream-shim.js, not this package

package-lock.json regenerated with the pinned toolchain (Node v25.9.0 / npm 11.12.1 via .nvmrc).

Deliberately left in (flagged by tooling but verified live or intentional)

• @babel/core (demo) — peer dependency of @rolldown/plugin-babel, used in demo's vite.config.ts
• @types/sax (archive-reader) — xmldoc's bundled xmldoc.d.ts does import { SAXParser } from "sax", so tsc needs these types
• buffer devDep (archive-reader) — local install of the package's own optional peer dependency for tests
• root reactjrx — mirrors the root rxjs: "*" single-instance/dedup convention
• All unused-export findings in published packages — potentially external API surface, out of scope for this sweep

Verified remainder (not shipped to keep the PR reviewable)

The same verification confirmed 11 more dead files in apps/front (~530 lines), left for a follow-up sweep: src/components/ui/{avatar,checkbox,close-button,dialog,drawer,field,input-group,popover,radio,slider,tooltip}.tsx (front only uses button, color-mode, provider; close-button is imported solely by the dead dialog/drawer/popover).

Gates

Baseline recorded on a clean checkout of the base commit (4e97270), then re-run after deletions:

• npm run build (18 projects) ✅
• npm run tsc (8 projects) ✅
• npm run lint + npm run format (biome) ✅
• lerna run test vitest suites (15 projects) ✅
• Playwright (chromium + Mobile Chrome, the browsers available in the sandbox): 78 failures byte-identical before and after the change (pre-existing/environment-only; CI runs the full browser matrix on macOS) — zero new failures introduced

Docs: no gitbook/ update needed — checked; nothing deleted is public surface or documented behavior.
