Cross-workspace correctness fixes and lint cleanup

[kalevski]

Bug fixes:

• base/BPlusIndex: collect leaf IDs via authoritative tree descent instead of the post-COW-unreliable nextPageId sibling chain; normalize -0 → +0 on number deserialize.
• base/Vec2.negate: avoid producing -0 for zero components.
• base/SpatialHash.nearest: return null on empty set; honor maxDist as a hard ring-search cutoff.
• base/formatByteSize: treat sub-1-byte values as "0 Bytes".
• base/slugify: keep underscores as word separators.
• logging/StreamReporter: rotate only after the first line and on >= maxBytes.
• node/oidc: thread caller fetchImpl/headers/timeout/retry into JWKS retrieval via fetchWithOptions + createLocalJWKSet; bypass shared cache for custom headers too (confused-deputy/SSRF guard).
• web-components/dialog-base: include self + parent chain when collecting inert ancestors.

Lint/style:

• eslint: scope scripts glob to /scripts/; relax namespace/empty-interface rules for generated react-types.ts.
• Replace value-returning ternaries with if/else, let → const, function exprs → arrows; annotate intentional no-this-alias / empty-catch / require.
• Drop stale react-hooks/exhaustive-deps disables.

Tests:

• Stub navigator/crypto via Object.defineProperty (getter-only on modern Node).
• Mock phaser in GameObjectComponent test to avoid browser-global init.
• Correct Color luminance (#767676 ≈ 0.1812), DisjointSet count, PageCache LRU expectations.
