Speaker Range Crop v0.2.0

Features

• Vicanek matched (decramped) filter design replaces RBJ-cookbook biquads - the Linkwitz-Riley 4th-order response now tracks the analog prototype all the way to Nyquist
• LFE channels keep their low-frequency content - the high-pass side is bypassed on channels foobar2000 marks as LFE
• Component version is injected from the Meson project version
• just build-debug, just build-release and just release commands for one-step plugin builds

Sound

• 20 kHz low-pass stays active and accurate at 44.1 kHz, where the old bilinear design had to disable it above 0.45 x sample rate
• Exact -6.02 dB Linkwitz-Riley crossover point at the cutoff frequency
• Minimum-phase IIR processing with zero latency, double-precision state at all sample rates

Fixes

• Gapless playback no longer glitches at track transitions - filter state is kept across on_endoftrack/on_endofplayback and only reset on seek/stop
• No allocations or exceptions can cross the foobar2000 SDK audio callback - reconfiguration failures pass audio through and retry
• Config dialog uses an invariant numeric locale, resyncs edits with sliders on focus loss, and reports preset save errors instead of crashing

Other

• Unit tests migrated to Catch2 v3 via Meson WrapDB (decramping, LFE bypass, channel isolation, preset table coverage)
• Meson wrap SDK mode is now the default build flow
• LF line endings enforced repo-wide; clang-tidy output filtered to project code
