[Crazy RoboTaxi] Add live-edit gameplay UI and make effects persistent

[aidanfnv]

Closes #549

Split off from #553

• Adds a frame-aligned live-edit HUD showing active style, weather, coins, nitro, items, and obstacles.
• Adds clickable live-edit action buttons in a single column on the left side of the screen.
• Supports showing control mappings on the buttons, moving them into the general control hints, or hiding the buttons entirely.
• Hides the live-edit card when no visible status or actions are available, including map-context-only configurations.
• Moves live-edit text and status rendering into ImGui while retaining GPU compositing for in-world sprites.
• Adds an upper-left coin counter whenever coins are enabled.
• Awards 100 points per collected coin to the overall Taxi score and removes the separate coin score.
• Makes style and weather selections persistent until explicitly changed.
• Makes mystery items select a persistent style rather than a temporary style burst.
• Removes the obstacle hit counter while retaining the active obstacle count.
• Changes nitro to raise only the maximum speed, without multiplying acceleration or producing the associated vehicle pitch/lift.
• Ensures a configured nitro ceiling can never reduce the vehicle’s normal maximum speed.
• Updates live-edit attachment to match the current OmniDreams API.
• Changes weather presets from standalone replacement prompts to runtime prompt_suffix values.
• Composes weather as the authored map prompt, current map-context suffix, and weather suffix. This preserves the map’s scene identity while applying weather.
• Keeps styles on their existing full-prompt path and preserves the mutual exclusion between styles and weather.

Confidence Score: 5/5

The PR appears safe to merge; the remaining findings are non-blocking metrics-accounting and documentation issues.

Summary

This PR adds a frame-aligned ImGui live-edit HUD and clickable actions, integrates coin scoring into the taxi timeline, makes style and weather selections persistent, revises weather prompt composition, and changes nitro to affect only the speed ceiling.

• Live-edit pickups and HUD snapshots now advance at controller-frame boundaries.
• Style, weather, item, obstacle, and coin presentation behavior is consolidated into the live-edit runtime and UI.
• OmniDreams model attachment and prompt-suffix handling are updated for the current API.
• Changes made after the prior review also add automatic native dependency acquisition, windowed video decoding, and SwiftVR profiling propagation.
