fix(editor): improve duct routing and parametric controls

[sudhir9297]

What does this PR do?

• Rectangular and oval duct wall clearance

  • Issue: Rectangular and oval ducts could be placed partly inside a wall because placement clearance used only the profile height.
  • Fixed: Placement and wall attachments now use the largest profile dimension, with a small wall standoff for non-round ducts.

• Keep a run on its starting wall

  • Issue: Continuing a duct or pipe run could move onto another wall when the cursor crossed the room.
  • Fixed: The run stays constrained to the wall face where its first point was placed.

• Automatic endcap cleanup

  • Issue: Deleting a duct or pipe left its automatically generated endcap behind.
  • Fixed: Deleting a run removes its automatic endcap while preserving manually placed endcaps.

• Parametric inspector controls

  • Issue: Inspector groups and action buttons did not support the desired initial layout and grouping.
  • Fixed: Groups can specify their initial expansion state, and parametric actions use a two-column layout where appropriate.

How to test

1. Run the editor with bun run dev.

   • The editor should start at http://localhost:3002.

2. Draw round, rectangular, and oval duct runs against a wall.

   • All profiles should remain outside the wall, and continuing a run should stay on its starting wall face.

3. Delete a duct or pipe with an automatic endcap.

   • The automatic endcap should be deleted with the run; manually placed endcaps should remain.

4. Open a parametric inspector with multiple groups and actions.

   • Groups should use their configured initial state and actions should be laid out consistently.

5. Run bun run checks.

   • Formatting, lint checks, type checks, and the full type validation should pass.

Focused node tests: 27 passed.

Note

Medium Risk
Touches scene load race handling and distribution-run interaction logic; behavior changes for wall routing and delete cascades could affect existing projects.

Overview
Duct/pipe routing and cleanup get the bulk of the changes. Wall placement clearance for rectangular and oval ducts now uses the largest profile dimension (plus a small standoff) via ductSurfaceClearanceM, and multi-segment runs can lock to the wall face where the first point was placed until the user commits outward from that surface. Deleting a duct or pipe run cascades removal of automatic end caps only (findAutomaticRunEndCapIds), with tests covering manual caps.

Editor/inspector: ParamGroup gains optional defaultExpanded, wired through single- and multi-selection inspectors; parametric Actions use a two-column grid when custom actions exist. Scene loading passes the current attempt into load() so an older in-flight load cannot apply after a newer retry.

Deps: @pascal-app/plugin-pool moves from a vendor tarball to a pinned GitHub package; @react-three/test-renderer is added for new distribution-run tool tests.
