feat(deck): extract reusable luSpatial geographic query effect

[ibgreen-openai]

Goals

• Make the projection, grid, viewport, and radius-query integration reusable by deck.gl applications outside the Taxi Atlas example.
• Keep the render-only @deck.gl-community/luspatial root entry isolated from optional query and graph dependencies.

Changes

• Adds the opt-in @deck.gl-community/luspatial/query entry with LuSpatialGeographicPointQueryEffect, typed layer outputs, stable graph/counter IDs, and query statistics.
• Projects the interactive selection on the GPU, applies conservative viewport padding, guards asynchronous diagnostics against stale query generations, and makes diagnostics opt-in.
• Gives the effect explicit GPU resource ownership and idempotent destruction.
• Migrates the Taxi Atlas to the reusable effect and removes its example-local query implementation.
• Adds package-boundary, lifecycle, resource-cleanup, and browser WebGPU coverage plus the website source alias.

Verification

• nvm use — Node 22.22.1.
• Targeted Biome formatting/check — passed.
• Focused Node Vitest — 4 tests passed.
• Browser WebGPU smoke on a hardware adapter — 1 test passed.
• Standalone Taxi Atlas Vite production build — passed (904 modules transformed).
• git diff --check — passed.
• Source-only TypeScript check reported no diagnostics in the changed query source; the repository still reports a pre-existing unused @ts-expect-error in modules/core/src/adapter/luma.ts with this shared install.
• Full yarn lint fix, yarn build, yarn test, yarn website:build, and (cd website && yarn build) could not start in the isolated worktree because the current dependency install is unavailable; yarn install is blocked locally by registry 403 responses. Clean GitHub CI is the authoritative full gate.
• The complete radius-query smoke follows the geospatial suite's established software-adapter exclusion because integer-fp64 radius kernels are prohibitively slow under SwiftShader; full assertions still run on hardware WebGPU.

Stack

• Base: fix(experimental): keep spatial source-ID queries candidate-scaled #2922 (codex/luspatial-direct-source-ids).
• The real packed-source Taxi Atlas PR feat(showcase): stream packed taxi rows into Spatial Atlas #2924 should be rebased onto this PR after the lower stack lands.

Risks

• This is an experimental/private deck.gl-community package surface.
• The effect owns its command graphs and buffers; callers must call destroy() when they remove it outside deck.gl's effect lifecycle.
