Slate v2 Phase 10 Surface Freeze

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

Goal

Freeze the package-level public API/readme truth across:

• slate
• slate-dom
• slate-react
• slate-history
• slate-browser

Then align the repo-level replacement claim to that same surface.

Scope

• package README alignment only
• repo-level replacement docs alignment
• roadmap/docs sync for the active Phase 10 gate

Constraints

• no fake API removals
• no hidden package redesign inside docs
• describe what is stably usable now, what is lower-level but still public, and what the current replacement claim does not promise

Progress

• aligned package README/API truth across:
  • slate
  • slate-dom
  • slate-react
  • slate-history
  • slate-browser
• aligned repo-level replacement docs to the same package/family claim
• synced the Phase 10 roadmap stack so this is recorded as the first landed release-readiness slice
