Integrate Greater Realm pre-generation release foundation

[ael-dev3]

Summary

• integrates the reviewed Greater Realm continent/runtime stack, including the feat(atlas,realm): ship canonical Greater Realm pipeline and next-gen grass #193 lineage and subsequent security, recovery, living-world, gathering, admission, and notification hardening
• prepares six sealed-to-Tier-I regions, 600 balanced server-assigned castle slots, four Workers per founder, and ample Food/Wood/Stone/Gold sites while preserving current gathering state
• includes bounded animated water, river boats, roads, bridges/fords, NPCs, wildlife, vegetation, and accessible atlas controls without claiming persistent player travel
• keeps the exact currently approved V4 entry-agreement bundle selected and removes the unapproved Realm Chat V5 proposal from the current release tree
• binds later Pages, bridge, Hermes, evidence, import, activation, notification, and admission steps to exact protected source and private receipts

Current release state

This is an audited pre-generation integration foundation, not a live Greater Realm claim.

• Greater Realm release verifier: pre-generation
• Pages deployment classifier: closed-review
• selected Entry Agreement: approved 2026-07-31-hegemony-entry-agreement-v4
• package, Mini App metadata, and in-game patch notes remain truthful at Alpha 0.3.43
• module import, module activation, client/server Greater Realm presentation, notification presentation, bridge preparation, Hermes execution, Inner Keep, and Realm Chat gates remain exact false
• all prepared/private/root notification bindings remain null
• no production publish, import, activation, notification, admission, Pages deployment, or live mutation is claimed by this PR

Keep this PR draft until exact-head checks are green and the audited true-merge ancestry procedure is ready. Do not squash or rebase: protected receipt authority depends on the retained candidate/anchor ancestry.

Validation

• independent V4 functional audit: P0=0, P1=0, P2=0
• independent exact refreeze audit: P0=0, P1=0, P2=0
• approved V4 Terms/Social Contract/Privacy bytes and policy hashes match the protected live V4 baseline
• 460 focused V4/release tests, 279 Hermes/activation tests, and 97 closure/workflow/legal tests passed
• TypeScript project checks and production build passed
• Greater Realm public boundary passed across 1,958 tracked paths
• protected source closure verified all 300 members; workflow pins and the empty protected-identical anchor were independently recomputed
• prior exact-head hosted verify and auth-bridge jobs passed after the CI portability/public-boundary fixes; final-head checks must also pass before merge

Superseded drafts and sequencing

The umbrella candidate subsumes or safely adapts #181, #182, #183, #190, #193, and #194. They must not be merged separately. #178 remains useful only as deferred future Realm Chat legal work; its unapproved V5 bundle is not selected by this release.

After #195 is safely merged and the controlled live rollout is proven, close the superseded PRs with references to the canonical main/live receipts. Resolve #193 last, preserving it as the final integration record.
