Encode edge-case semantics explicitly in tree traversal and recovery logic

Summary#

Bugs around empty containers, text-only siblings, deep nesting, and retry paths usually come from implicit assumptions about node types or control flow. Make edge-case semantics first-class in the implementation, define explicit fallbacks and warnings, and test retry/recovery behavior separately from the initial execution path.

Problem#

DOM traversal and server rendering logic failed in uncommon cases such as empty fragments, text siblings, or deep-tree retries after stack overflow recovery.

Solution#

Model handled node/state types explicitly, add deterministic fallback behavior for empty or non-host cases, and extend recovery logic so retry paths preserve the same guarantees as first-pass rendering.

Failure Modes#

Assuming only one concrete node type matters and skipping text, fragment, document, or shadow-root cases
Fixing the initial traversal path but leaving retry or hydration paths behaviorally different
Relying on incidental test coverage instead of adding focused cases for empty, nested, and overflow scenarios
