Slate-v2 Rename Cut

Supporting plan. For current queue and roadmap truth, see master-roadmap.md.

Goal

Rename the surviving replacement-candidate stack in /Users/zbeyens/git/slate-v2 from transitional *-v2 names to final names.

Scope

• package directories and package names
• imports, tsconfig refs, rollup config, workspace deps
• example/test filenames and route ids
• clipboard/browser payload naming
• docs/spec references in plate-2 Slate v2 docs

Non-Goals

• no new runtime features
• no React 19 behavior work beyond trivial fallout
• no benchmark widening

Acceptance

• no remaining live references to slate-v2, slate-react-v2, slate-dom-v2, or slate-history-v2 in the active source graph except intentional historical docs
• install/build/type/test/browser proof survives on the renamed graph

Progress

• renamed surviving package directories in /Users/zbeyens/git/slate-v2/packages to final names:
  • slate
  • slate-react
  • slate-dom
  • slate-history
• renamed surviving example, component, and Playwright filenames away from the old slate-v2-* pattern
• rewired imports, tsconfig refs, rollup config, workspace deps, example ids, and browser payload naming to the final names
• verified the renamed graph with install, example typecheck, rollup build, runtime tests, Next build, and local browser proof
