glm-5.1 c9c32a6aa6 decompose reconciler roadmap into 20 implementation tasks across 5 phases

Tasks follow the architecture spec phases:
- Phase 0: key field on UElement (2 tasks + review)
- Phase 1: reactive-host bridge / fiber tree (4 tasks + review)
- Phase 2: key-based children reconciliation (3 tasks + review)
- Phase 3: unmount & dispose support (4 tasks)
- Phase 4: TypeBox value optimizations (4 tasks)

Validated with taskgraph CLI: no cycles, 15 parallel generations,
3 high-risk tasks identified (signal-driven-updates, commit-mutations,
fiber-disposal).

Description

Refactor the existing mountNode in src/host/config.ts to build a fiber tree alongside host instances during the mount phase. Currently, mountNode creates instances but discards them — the instance tree is unreachable for updates. After this task, Root holds a reference to the root fiber, enabling re-render and unmount.

The mount pipeline stays the same (depth-first, post-order append). The change is that each created instance is wrapped in a Fiber node that tracks its parent, children, and props. Function components remain transparent — they don't get their own fiber.

This task also stores the root fiber on the Root object so that subsequent renders can diff against it.

Acceptance Criteria

mountNode creates Fiber nodes for each intrinsic element and text instance
Function components are transparent — no fiber for the component itself
URoot children are mounted into the parent fiber (root is a transparent container)
Primitives get text fibers with tag: "#text"
Fiber tree is linked: parent and children fields are populated
Root object holds a rootFiber reference (new field)
signalDisposers initialized as empty array on each fiber
effect initialized as null on each fiber
Existing mount behavior preserved — hosts still receive same createInstance/appendChild calls
Existing tests pass
New test: after render(), Root.rootFiber has correct children structure matching the UNode tree
