Merge the display/ and render/ sibling modules into a single render/
module with display/, sprite/, and ddraw/ sub-modules. Pure mechanical
refactor — file moves and import rewrites only, zero logic changes.

feat: port Music streaming audio system to pure Rust
Replace WA's Music/StreamingAudio system with a pure Rust implementation
using hound for WAV parsing and DirectSound for streaming playback.
Music system (0x354-byte object, vtable 0x66B3E0):
- Unified Music + StreamingAudio into single struct with full field map
- 6-slot vtable fully replaced via vtable_replace! macro
- Constructor hooked (0x58BC10), destructor uses wa_free
- Playlist management, track ID-to-filename mapping (1-13)
- Volume control with dB lookup table, using Fixed type
Streaming engine:
- WAV streaming via hound + BufReader<File> (replaces mmio API)
- DirectSound double-buffered ring buffer with timeSetEvent refill
- Buffer size matches original formula (timer_delay * avg_bytes/1000)
- advance_track guards against premature track changes (checks
IDirectSoundBuffer::GetStatus before advancing)
Sound hooks:
- Hook PlayWormSound, StopWormSound, LoadAndPlayStreaming
- Remove old streaming.rs stub, update GameSession to use *mut Music

refactor: split input.rs into frame_hook, replay_test, debug_utils
The old input.rs was a grab-bag of unrelated concerns. Split into:
- frame_hook.rs: TurnManager_ProcessFrame hook, debug_sync, watchpoint
arming. Always installed (including baseline/trace-desync mode).
- replay_test.rs: Fast-forward + gameplay milestone tracking. Only for
headful replay testing — headless runs at max CPU speed already.
- debug_utils.rs: dump_region memory inspection (used by validation).
Moved get_ddgame()/get_wrapper() to openwa-core::engine::game_session
as shared #[cfg(x86)] accessors, eliminating duplicates in wormkit
and debugui.

feat: add #[derive(FieldRegistry)] proc macro for auto-generated field maps
New openwa-derive crate with FieldRegistry proc macro that generates
HasFieldRegistry impls for #[repr(C)] structs. Uses offset_of!() and
size_of() for compiler-verified offsets. Fields prefixed _unknown/_pad
are automatically excluded.
Applied to 5 key structs: DDGame, DDGameWrapper, GameSession, CTask,
CTaskWorm. Each now has a field_registry() -> &'static StructFields
method for runtime offset-to-name lookups.
This lays groundwork for typed vtable derive macros using the same
proc macro infrastructure.

fix: remove extra loading progress ticks, cargo fmt
Reduce from 4 to 2 DDGameWrapper__LoadingProgressTick calls, matching
the original constructor. Tick counter +0x04D8 now matches exactly
(0x334). All DDGameWrapper fields match the original.
Remaining headless checksum mismatch is likely due to headless display
handling differences (our headless display is non-null vs original's
NULL display parameter).
