33 (G2/G3): the stick reels the world; api.claimInput('sticks'); every level + level tabs in the VR pause menu

[AlexZ005]

Roadmap 33, lane 33-modules — the core hooks Untangle needed (items G2, G3 of lanes/33/user-feedback-2026-10-01b.md). Pairs with the modules PR (untangle 2.4.0). Do not merge from the lane — the integrator merges.

G2 — "stick up/down moves it farther/closer, just as in edit mode for objects"

• World reel: the one-hand world pan (right grip on scenery/air — Edit, or Interact with play.locomotion.worldGrab) now reels the world on that hand's stick Y with Edit's own object reel (grabStickAdjust): forward pushes it away along the hand's ray, back pulls it in, from the distance to the gripped spot. worldReelStep is pure + exported.
• api.claimInput('sticks'): both VR sticks' navigation stands down (left move, right snap/smooth turn + teleport) while a module reads the sticks (Untangle's held globe: Y reels, X scales — Edit's mapping). claimInput now answers true for a scope the core knows, so modules feature-detect it.

G3 — the pause menu's Levels page in a headset

• The VR Levels page drew list.slice(0, 20); Untangle has 30. Now a 6-column grid as tall as fits, pages with arrows beside Back beyond that (≤ 20 levels and no tabs keep the old 5 × 4).
• addSetting({type: 'choice', onLevels: true, ...}) also draws the choice as tabs above the Levels grid, desktop (role=tablist) and VR (shell:tab hits). Untangle's Board (Globe / 2D board) uses it.
• The module's own picker being invisible over core's VR panel was a draw-order tie (K2 re-stamps every api.vrPanel object to PANEL_ORDER; three then sorts by bounding-sphere centre). That's fixed in the module, so it works on 1.18 too. A core way to layer a module panel over core's is a DEVX candidate, not in this PR.

modules flights on this core	untangle-vr2 94/0 (S: left X → Levels → Board tabs → a level), untangle-vr 98/0, untangle 71/0, untangle-drag 54/0

fakeXR controllers don't follow the reference space (a headset's do), so vr-world-reel poses a spec-accurate right hand re-derived on every setReferenceSpace. OWED on a Quest: the reel's feel (3 %/frame at full stick, Edit's rate), the tabs' legibility at 1.2 m.

CHANGELOG lines (for the integrator)

• 🎯 Push and pull with the stick. Holding the world with one grip, push the stick up to send it away and down to bring it closer, just as with an object in Edit. Games use the same gesture for what you hold (Untangle's globe).
• 🗺️ Every level in the headset menu, and a game's own choices (Untangle: Globe / 2D board) as tabs above the levels.
• 🧩 SDK: api.claimInput('sticks') (both VR sticks; returns true when supported); addSetting({..., onLevels: true}).
