v0.2.0 — Dynamic EQ bands

8-band zero-latency parametric EQ + feed-forward compressor + I/O trim, now with
per-band dynamic EQ.

New in this release

• Dynamic EQ: any gain-having band (Bell/Shelf/Tilt) can run as a frequency-selective
  compressor/expander — threshold, ratio, attack, release, range, and a Downward (duck)
  or Upward (boost) direction. No lookahead, zero added latency preserved.
• Live curve indicators showing which bands are dynamically engaged and by how much.

Verified

• pluginval (VST3 + AU, strictness 5): clean pass.
• Hosted successfully in REAPER (real DAW).
• Real audio processed through the actual shipped processor class confirms both EQ
  shaping and dynamic ducking/boosting match analytically-predicted values closely.

Known limitations

• No preset system yet.
• Meters are simple peak reads, not ballistics-accurate.
• Dynamic EQ detection is internal only (no external sidechain input yet).
• Not yet tested against real audio hardware in a live signal chain.

Next up: harmonic-based EQ.
