v0.4.0

Release 0.4.0

v0.3.2

Run as background daemon by default

`cante run` now forks a supervisor process, redirects its output to
~/Library/Logs/cante.log, records its pid in /tmp/cante.pid, and
returns the terminal. The supervisor calls setsid() when its stdin
isn't a tty so it survives terminal close.

`cante stop` reads /tmp/cante.pid and SIGTERMs the supervisor (which
cleanly terminates the overlay and the Spotify poller via the
existing signal handlers). It still falls back to the overlay-only
stop when no supervisor pid file exists.

`cante run --foreground` / `-f` keeps the previous attached
behavior for interactive debugging.

v0.3.1

Add Makefile with release target

`make release VERSION=x.y.z` validates state, tags cante, waits for
the GitHub Actions release workflow to publish the arm64 tarball,
then updates Formula/cante.rb in the homebrew-cante tap (path via
HOMEBREW_CANTE_DIR, defaults to ../homebrew-cante) and pushes.

v0.3.0

Add size and single-line overlay options

--size small|medium|large scales the whole overlay (fonts, padding,
box dimensions) together. --single-line hides the next-lyric line
and folds loading / missing-lyrics status into the main line.

Also make 'cante --flag' equivalent to 'cante run --flag'.

v0.2.0

Add text-shadow and opaque overlay options

Both default to off so existing users see no change. Persistent
defaults can be set in ~/.config/cante/config.json; CLI flags
override the file.
