feat(wall): typed exact length during two-click wall drafting

[dkbbdev]

Closes #308.

What

While drafting a wall in the two-click flow, typing an exact length (e.g. 3m, 180cm, 2500 in mm notation, 10'6") now locks the draft to that length along the current draft direction — the pointer keeps steering the direction only.

• Enter commits the wall at the typed length.
• Escape is two-stage: first press clears the typing buffer, second press cancels the draft (per the triage note on unit toggle only affects the display of dimensions, not the input #308).
• Backspace/Delete edit the buffer.
• The HUD label shows the buffer while typing and falls back to the normal drafting label when empty.

How

• New shared store useWallDraftTyping (packages/editor/src/store/use-wall-draft-typing.ts) holds the buffer so the 2D floor-plan draft and the 3D wall tool stay in lockstep per the 2D ↔ 3D parity rule in wiki/architecture/tools.md.
• 3D (packages/nodes/src/wall/tool.tsx): a window keydown listener mirrors the cabinet tool's applyTypedDimension pattern — parseMeasurement resolves the buffer with the same bare-unit defaults; grid:move projects the draft end onto the typed length; Enter synthesizes a grid:click at the projected endpoint so the normal commit pipeline (chain continuation, auto-close, support-slab election) runs unchanged.
• 2D (floorplan-panel.tsx): the same projection in the wall-draft pointer move, the same key handling in the window keydown effect, and the HUD label override.
• Angle snap / junction snap / magnetic alignment continue to work on untyped drafts; the typed commit intentionally bypasses endpoint snap so the typed length survives exactly (drafting direction is taken from the current snapped pointer, so snapped angles still steer it).

Testing

• packages/editor/src/store/use-wall-draft-typing.test.ts — buffer lifecycle + accepted keys.
• packages/nodes/src/wall/typed-length.test.ts — the projection math shared by both views.
• Full @pascal-app/editor + @pascal-app/nodes suites pass (turbo run test: 3119 tests across 268 files, plus the editor suite).
• tsgo --noEmit clean for both packages; biome check clean on touched files.

Verified end-to-end on a self-hosted deployment (design.dekorproduct.com) in both the 2D plan and 3D views with metric-m and mm notations.

Thanks for the detailed triage spec on #308 — the interaction follows it point by point.

Note

Medium Risk
Touches core wall placement/commit paths in 2D and 3D with global key handlers and intentional snap bypass on typed commits; regression risk is localized to drafting UX rather than persisted data.

Overview
Adds typed exact-length input while drafting walls in the two-click flow (#308), with matching behavior in 2D floor plan and 3D wall tool.

A new shared Zustand store (useWallDraftTyping, exported from @pascal-app/editor) holds the measurement buffer and a projected endpoint so preview, HUD, click, and Enter commit stay aligned. While typing, the draft end is projected onto the parsed length along the pointer direction; the length label shows the buffer instead of live distance. Enter commits at that length (3D via synthetic grid:click; 2D via wallPlacementPointRef to avoid stale closures); Escape first clears the buffer then cancels the draft; Backspace/Delete edit the buffer. Typed commits skip endpoint re-snap so the entered length is preserved; the buffer clears after each segment so chains do not inherit a stale length.

Unit tests cover the store/key filter and the shared projection math.

Stale Bugbot comment from a previous run.

Addressed all 5 Bugbot findings in 11e8fa5:

• Click commit ignores typed length / Enter re-snaps typed endpoint — the typing store now carries the projected endpoint (projectedEnd); click and Enter commits reuse it verbatim in both 2D and 3D, bypassing magnetic/angle/grid snap so the committed wall is exactly the previewed length.
• HUD ignores typing store updates — the 2D layer subscribes to the store (useWallDraftTyping((s) => s.input)) instead of reading getState() inside useMemo.
• Typing buffer persists after commit — clearInput() now fires on every exit path: 3D commit, 2D commit + chain continuation, clearWallPlacementDraft, cancel; removed the unused begin().
• 2D typing keys leak to shortcuts — typing/Enter/Escape handlers now stopPropagation() as well as preventDefault().

Full check-types + test suites pass (3,125 tests).

Round 2 findings fixed in 596c7e7:

• 3D Enter re-snaps the typed endpoint — the buffer now survives the synthetic grid:click (commit recognized as typed, snap bypassed), with a defensive clear after in case the commit path bails early.
• Stopped draft keeps typed buffer — stopDrafting clears the typing store, so double-click finish and chain auto-close no longer leak the old length into the next draft.
• 2D Enter uses a stale callback — the placement callback is now kept current via a useEffect latest-ref instead of self-assigning on first call; typed Enter commits the wall instead of restarting the draft. The 2D move preview also publishes projectedEnd so a click mid-type commits the projected endpoint, matching 3D.

check-types + biome + full test suite pass.

Click commits stale typed length

High Severity

append and backspace only change input. The draft end and projectedEnd update on pointer move, so a click after typing reuses the last pointer point. Enter recomputes the projection and commits the typed length; click does not. The HUD already shows the buffer, so the committed wall does not match the previewed length.
