feat(plan): add Plan tab as the first project surface

A new home for everything that happens BEFORE building:
- Vision    — one-line elevator pitch (mirrors productVision)
- Ideas     — the "park-it" bin for raw thoughts
- Tasks     — what needs to happen next (open / done)
- Decisions — log of "we chose X over Y because Z"

Storage is appended under fs_projects.data.plan so no schema migration
is needed. CRUD lives at /api/projects/[projectId]/plan.

The bare project URL now redirects to /plan instead of /product, and
the AI chat receives decisions + open tasks in its active-project
context block — so it stops re-litigating settled questions and knows
what's queued up.

/**
* /api/projects/[projectId]/plan
*
* Project-level "thinking" surface — the home of the Plan tab.
* Stores everything that happens BEFORE building:
* - vision — one-line elevator pitch (mirrored to data.productVision)
* - ideas — unstructured capture (the "park-it" bin)
* - tasks — what needs to happen next (status: open | done)
* - decisions — log of "we chose X over Y because Z"
*
* Storage lives under fs_projects.data.plan.{ideas,tasks,decisions}
* so we don't need a schema migration. Items are appended-and-mutated
* in place; we never load the full document back to the client without
* an ownership check.
*
* Methods:
* GET → full plan snapshot
* POST { kind: "vision", text } → set vision (also mirrors to productVision)
* POST { kind: "idea", text } → add idea
* POST { kind: "task", text } → add task (status="open")
* POST { kind: "decision", title, choice, why? } → add decision
* PATCH { kind, id, ... } → update one item (toggle task, edit text)
* DELETE?kind=…&id=… → remove one item
