feat(cantina): integrate M3 runtime vertical slice

[colorpulse6]

Summary

• integrate the production-reviewed Cantina bundle as a reusable, data-driven colony interior with its authored 12x10 layout, wall/floor/ceiling/facade art, four props, and normal colony commissioning/access
• add deterministic two-period bartender, regular, and signal-chaser schedules; portrait dialogue; stable authored rumors; and a fixed-price House Pour service with transient success/failure feedback
• add a deterministic SEED CANTINA DevPanel fixture plus production gameplay evidence at an exact 480x854 viewport

Design boundary

This is the approved Cantina-first M3 vertical slice. It keeps runtime ownership in the existing colony/interior, first-person renderer, and Game.tsx persistence seams. No new persistent fields or save migration were required.

• Approved design spec
• TDD implementation plan

Verification

Fresh final verification at 303c7d144f705df168628f8232f0656c6a6ca5b4:

• npx tsc --noEmit: pass
• yarn colony:test: 301/301
• yarn engine:test: 309/309
• yarn sprites:test: 8/8
• yarn build: pass; static pages 6/6, export 3/3
• NEXT_PUBLIC_DEVTOOLS=1 yarn build: pass; static pages 6/6, export 3/3
• two independent final reviews: no critical or important findings

Production playtest

At exact 480x854 CSS pixels in Chrome 150 (DPR 1):

• commissioned Cantina through the real colony menu for 200 metal

• completed three mission-cycle result flows until operational

• descended, entered the real exterior door, and exited normally

• verified all three scheduled roles, portraits, four props, reviewed environment art, stable repeat-entry rumor, and visual-only terminal

• verified House Pour 5 -> 0 with green HOUSE POUR SERVED, then 0 -> 0 with red PURCHASE UNAVAILABLE; no item, buff, or quest was created

• console errors, page errors, and warnings: 0

• Playtest receipt

• 480x854 gameplay screenshot

Explicit non-goals

Marketplace, Town Hall, bulletin-board quests, Atlas-to-colony routing, colony-tier promotion, district growth, political systems, and broader M3 hub asset registration remain outside this slice.

This PR remains draft until the full main-base workflow is green. Do not merge without fresh user approval.
