v0.0.2 - UI & Building Systems

Features

• Resource HUD with WW1-themed pixel art icons
• Build menu with placement preview overlay
• Building/tree selection with info panel and train button

Fixes

• Spawn hang eliminated (bounded retry + spiral fallback)

• Placement validation mirrors Rust logic exactly

Performance

• Cached resource HUD values
• Build menu buttons only update on change
• Tree wobble early-out
