v0.0.7 - widescreen sequence and presentation fixes

Fix widescreen encounter and room presentation, including Bit/Byte landing, single boss doors, factory backgrounds, isolated boss arenas, Kaiser's head, and final-fortress entrance/shaft framing.

This release freezes the fixes covered by the completed owner playtests and retained automated checks. Widescreen remains available from the launcher's Mods page. Broader route/audio coverage and shared-engine integration are tracked separately.

The Windows package includes the launcher assets and runtime dependencies, with tracing and instruction-debugger instrumentation disabled. Supply your own Mega Man X3 USA ROM; ROMs, saves and developer settings are not included.
