v0.5.0

Added

• eqtune preset-show [name] prints the active or named preset's preamp and bands
  without switching presets or changing configuration.
• eqtune limiter on|off now toggles the global soft limiter from the CLI, persists the
  setting immediately, and applies it live without creating an unsaved tuning session.
• eqtune completions bash|zsh|fish generates shell completion scripts directly from
  the CLI definition without contacting the daemon.

Changed

• The obsolete auto_follow_new_devices config field has been removed. Output-device
  following remains always on; older configs containing the unused key continue to load,
  and the key disappears on the next config save.
• The build now renders the embedded Info.plist from a template using the Cargo package
  version, so macOS metadata cannot drift behind the released binary version.

Fixed

• Sustained-silence processing now clears biquad delay memory before skipping DSP work,
  preventing an old low-frequency or high-Q filter tail from reappearing when playback
  resumes.
• Live band insertions, removals, and edits no longer let a band inherit filter state from
  a different band that previously occupied the same cascade index.
• The Core Audio shim validates matching interleaved stereo Float32 input/output formats
  before starting and safely rejects an unexpected runtime buffer topology instead of
  reinterpreting arbitrary device buffers as floats.
• Config loading now rejects and preserves configs with an empty preset library or a
  missing active preset instead of accepting a state that normal tuning commands cannot use.
• CLI control connections now use read/write deadlines, cap daemon replies at 1 MiB, and
  report an empty reply, preventing a stuck or invalid daemon from hanging or growing the
  client without bound.
