refactor(skin): remove legacy skin implementation

[mihar-22]

Summary

• remove the superseded Default and Minimal legacy CSS and Tailwind source graph, including the transitional React Tailwind skin sources
• keep @videojs/skins as the private VJSC source and generator owner while removing its obsolete publish build
• remove legacy snapshots, browser-comparison coverage, and obsolete Tailwind-migration agent skills
• simplify framework CSS tooling and the skin preview now that every consumer uses VJSC output
• replace legacy/VJSC comparisons with durable CSS and Tailwind output contracts
• preserve ignored framework intermediates and verify public package and CDN artifacts contain no compiler dependencies

Verification

• React, HTML, Skins, and site unit suites
• pnpm build:packages
• pnpm build:cdn
• pnpm -F @videojs/html check:cdn
• pnpm build:sandbox
• Astro check and full site build
• packed HTML/React source and compiler-isolation audit
• pnpm check:workspace

Closes #2495
Parent: #2185

Stack

• Depends on refactor(skin): cut internal consumers over to VJSC #2548.
• Followed by docs(site): document Shadcn registry workflow #2549.

Note

Medium Risk
Large removal across presets, CSS bundling, and broad E2E parity coverage; regressions would show up as skin/CSS/Tailwind drift or broken CDN/HTML skin builds rather than auth or data risks.

Overview
Removes the legacy Default/Minimal skin stack and everything that still depended on it, so skins and tests treat VJSC as the only implementation path.

E2E and CI drop ejected-skin generation, sync-ejected-skins, and HTML/React ejected fixtures; video control and visual suites no longer cover those pages. VJSC styling parity tests compare CSS vs Tailwind only (no source=legacy), with layout contracts leaning on ARIA roles instead of legacy media-* class hooks. Live-video caption tests now always expect menu-based captions.

React package deletes the transitional *skin.tailwind.tsx presets and the @videojs/skins dev dependency. HTML build CSS plugins no longer scan or resolve @videojs/skins/ imports—only relative @imports under each package’s src/.

Agent/docs cleanup: Tailwind migration skills and their references are removed from .agents/skills/ and AGENTS.md; design notes point preset styling at packages/skins/vjsc/.

ℹ️ How to interpret

Each entry is independently bundled, minified, and brotli-compressed. Initial size includes its static import graph; lazy dynamic chunks are reported separately.

Entries are not additive because their dependency graphs overlap. Preset rows represent realistic combined bundles.

Changes of 300 B or less across initial, lazy, and total size are collapsed, not discarded.

Run pnpm size locally to check current initial sizes.
