feat(rate): add matched regional surface plan editors

[d-sorgcodexagent]

Summary

• add matched PyQt6 and React Ground Surfaces modules for a complete SI base material/domain and 1–8 regional overlays
• expose IDs, precedence, finite bounds, source revision, all v1 material inputs, explicit target-frame geometry, and accessible validation/readback
• derive provenance SHA-256 from the actual editor draft and pin Python/TypeScript parity
• delegate both clients to the strict regional request validator from feat(ground): add regional material plan wire contract #4335; TypeScript does not run or duplicate ground physics
• disclose that initial values are illustrative/unvalidated and that this slice is session-only validation, not calibrated course data, execution, or playback
• preserve the corrected feat(ground): add regional material plan wire contract #4335 head through normal merge commit 6051d89a685ef009cfeef7c77bb3591cd124574a; no history rewrite
• update navigation/help, specifications, manifest, and all canonical handoffs

Verification

• Python adapter: 3 passed post-parent merge; earlier combined Python/PyQt editor: 5 passed, including 2 GUI cases
• PyQt shell/help: 6 passed
• final React editor + wire: 9 passed; navigation/view preferences: 12 passed; help: 3 passed
• TypeScript, full and focused zero-warning ESLint, Vite production build (198 modules): passed
• Ruff, MyPy, manifest validator + 8 manifest tests, docs governance, changed-test assertions, staged secret scan, exact-base file-size/changed-Python/diff/ancestry checks: passed

Validation boundary

A separate post-merge regional PyQt rerun and an ad hoc full-shell exit check timed out during workstation startup/lifecycle with no assertion output and are not claimed. Request import/export, measured calibration, workspace model-input persistence, execution/result playback, terrain/interval visualization, compiled/TypeScript regional physics, UpstreamDrift parity, protected CI/review, and release remain open. This does not close #4274 or #4267.

Advances #4274 under epic #4267. Depends on #4335.

Exact-head rendered QA follow-up at cbb9c0a:

• fixed stale canonical validation evidence after any identity, interval, material, add, or remove edit on both PyQt6 and React;
• added specific PyQt6 engineering-context tooltips after the complete tooltip contract exposed the new controls;
• browser-proved validate -> add overlay clears readback -> remove/revalidate restores the one-overlay digest;
• 870 Python/PyQt tests and 672 React tests pass;
• Ruff/format/MyPy, TypeScript, zero-warning ESLint, 198-module production build, manifest/docs/file-size governance, and diff checks are green.

The polynomial-generator empty-legend warning is pre-existing and unrelated. Fresh protected checks are queued. This does not claim completion of #4274: import/export, persistence, execution, playback, measured calibration, and consumer parity remain open.

Consolidated into #4410. Closing to reduce CI/CD runner load.
