Automatic gain control was always on with no way to turn it off. Toggle
it with F12, the /agc command, or the agc FIFO command, and persist the
choice in the configuration file the same way noise suppression does.
AgcEnabled defaults to true so existing setups keep their current
behavior, and the saved value is applied to the stream on connect. The
enabled flag becomes an atomic.Bool because the capture goroutine reads
it while the UI goroutine writes it, and the lazily created right
channel AGC now inherits the left channel's state.

setTransmit, OnMicVolumeUp, OnMicVolumeDown, and the file-playback
auto-transmit path all dereferenced b.Stream without checking for nil.
In tone-test mode b.Stream is never set (OpenAL is skipped), so guard
all call sites.
Make the F11 action menu close through a shared close action so Escape and the explicit Close actions menu item follow the same path. Treat Escape-prefixed Up and Down events as close inputs while the action menu is active, which handles termbox InputAlt behavior after pressing Escape. Preserve and restore the user/channel tree selection across action menu open and close, and preserve selection across live tree rebuilds.
Tested with: GOCACHE=/tmp/barnard-go-cache go test ./...
Implements 7 voice effects that can be cycled through with F12:
- None (default)
- Echo: Single repeating delay with feedback (250ms)
- Reverb: Multiple short delays without feedback
- High Pitch: Chipmunk voice using cubic interpolation
- Low Pitch: Deep voice effect
- Robot: Ring modulation for robotic sound
- Chorus: Layered voices with pitch variations
The effects are applied after noise suppression and AGC in the audio
pipeline. Selected effect is persisted to config file. Includes
comprehensive documentation in README.

This addresses low microphone volume issues by automatically normalizing
outgoing audio levels with dynamic range compression and soft limiting.
The AGC is always enabled and applies voice-optimized parameters to
ensure consistent audio levels are sent to other users while preserving
manual volume control for incoming audio.
