feat(ground-study): prepare jobs from current editors

[d-sorgcodexagent]

Summary

Advances #4369 as the next protected child after #4373.

• adds a strict bounded preparation-request/v1 contract and Python-authoritative registered-profile job builder
• prepares from the current validated launch, variation, and ground-surface editors without retaining, enqueueing, or running the job
• gives PyQt6 and React an explicit Prepare -> Review/Save -> Confirm -> Run workflow; preparation never auto-submits physics
• invalidates prepared editor snapshots on relevant input drift while preserving historical results and imported immutable jobs
• binds authority responses to the exact captured request and preserves tee/ground setup, wind, provenance, digests, and explicit UNVALIDATED calibration evidence
• updates SPEC, campaign manifest, and all canonical handoffs in the implementation commit

Human review was accepted by the campaign owner; this PR still relies on ordinary protected repository checks and dependency order.

Local validation

• python -m pytest tests/rate_of_closure -q -n 8 — 1,223 passed
• consolidated Python authority/profile/preparation/UI regressions — 134 passed
• post-review PyQt preparation/simulation regressions — 49 passed
• React Vitest — 137 files / 905 tests passed
• React TypeScript, zero-warning ESLint, and production build — passed (229 modules)
• changed-source MyPy under Python 3.11 — passed
• Ruff check and format — passed
• module-size budget — passed
• campaign manifest validation and 8 manifest tests — passed
• git diff --check — passed

Release notes

The protected pinned MyPy/CI run remains authoritative. The local Python 3.13/MyPy 1.13 compiled binary hit an internal cache-serialization assertion; Python 3.11/MyPy 2.1 completed cleanly. A default 14-worker full-suite stress run also encountered two loopback poll timeouts on the loaded workstation; the isolated tests and complete eight-worker suite passed.

Consolidated into #4409. Closing to reduce CI/CD runner load.
