Fix: reconcile live expedition state without rebuilding the Realm

[ael-dev3]

What changed

This is PR A of the four-worker release train. It keeps live gathering updates inside one persistent Realm scene.

• Split immutable Gold/Food/Wood/Stone site catalogs from occupation-bearing live rows in RealmMapScreen.
• Add RealmSceneHandle.reconcileLiveGatheringState so resource layers update occupation rings, wagons, and telemetry in place.
• Preserve static models, pick volumes, renderer, camera controller, pointer listeners, labels, and selection across public occupation updates.
• Add guarded reconciliation that rejects malformed topology/dynamic snapshots and retains the last valid presentation.
• Add development QA attestation for scene build sequence, canvas/scene identity, camera mode/pose/target/FOV/zoom, and selection.
• Add a deterministic regression test and a dated worker-system plan.

Why

Before this change, the scene-construction effect depended on goldNodes, foodNodes, woodNodes, and stoneNodes. Those arrays intentionally changed when occupation phase, timestamps, or origin-castle state changed. A successful dispatch therefore disposed and rebuilt the entire WebGL scene, called setCameraMode('realm'), and could leave the player in the reported overview-like camera state until reload.

The scene-construction effect now depends only on stable site topology. Live occupation updates reconcile through the persistent scene handle and never call camera reset or renderer loading state.

Dependency / stack

This branch is intentionally stacked on the exact refreshed head of Stone Quarry PR #65:

• PR feat: add Stone Quarry gathering node #65: feat: add Stone Quarry gathering node #65
• Required base branch: agent/stone-quarry-node
• Required base SHA: de679623b6814d95e501000d11d7208c6318d86e
• Do not merge this PR before PR feat: add Stone Quarry gathering node #65. This PR does not retarget, merge, close, or rewrite PR feat: add Stone Quarry gathering node #65.
• Head SHA: 5d69e5e

Evidence

The new scene regression injects an outbound-to-gathering occupation update and asserts:

• scene build sequence unchanged;
• canvas identity unchanged;
• scene identity unchanged;
• camera mode, position, target, and zoom unchanged;
• one ordinary render occurs;
• accepted reconciliation telemetry increments.

Checks run:

• tsc -b
• vitest run: 181 files, 1,638 tests passed
• spacetimedb/tsconfig.json TypeScript check
• runtime asset verification (40 exact runtime assets)
• Gold/Food/Wood/Stone/Tree/Supply Wagon verification
• Vite production build
• production-output exclusion audit
• git diff --check

Scope boundary

This PR fixes scene stability and is not the generic four-worker authority migration. PR B will append the next schema generation after Stone v9, add exactly four server-owned workers per castle, generic dispatch/recall/claim, worker selection/roster UX, and the staged legacy cutover gate.

No SpacetimeDB schema, reducer, binding, production data, seed, deployment, or publish action is included here.

Superseded by merged PR #72. The live-state reconciliation work was integrated there with an atomic all-layer preflight so a later projection failure cannot leave the Realm partially mutated.
