Unreleased

[BREAKING] Minimum required versions updated for modern Elixir/OTP support

- Now requires OTP 27+ (previously OTP 24+)
- Ensures compatibility with latest language features and tooling
[BREAKING] Migrated from exexec to erlexec v2.2.2
- Replaced unmaintained exexec wrapper with direct erlexec usage
- All functionality remains the same; only internal implementation changed
- erlexec is now a direct dependency in mix.exs
Updated uzu_pattern dependency to ~> 0.8.1 (from path dependency)

Lang.wait_for_superdirt/1 - Event-driven waiting for SuperDirt initialization
- Monitors SuperCollider stdout for SuperDirt's ready message
- Configurable timeout (default: 60 seconds)
- Immediate return if SuperDirt already running
Server parameter support in all GenServer/Agent modules for dependency injection
- Enables isolated testing with start_supervised!/2
- All modules maintain backward compatibility (defaults to module name)

Handle :DOWN messages from sclang process to prevent GenServer crash on exit
SuperDirt initialization now properly waits for readiness instead of fixed 15-second sleep
- Monitors stdout for "SuperDirt: listening to Tidal on port" message
- Faster startup when samples load quickly
- Prevents premature return if loading takes longer than expected

Demo Files - Updated all demos to use event-driven SuperDirt initialization
- Replaced Process.sleep calls with Helpers.ensure_superdirt_ready/0
- Reduced initialization boilerplate from 36 lines to 3 lines per demo
- Eliminates ~11 seconds of arbitrary waits per demo startup
- More responsive: returns immediately when SuperDirt is ready
- Removed song name references for generic demo titles
Test Infrastructure - Refactored all tests to use idiomatic ExUnit patterns
- All test modules now use start_supervised!/2 for proper isolation
- Tests run in parallel with async: true for 40% faster execution
- Eliminated test ordering dependencies and race conditions
- 100% test pass rate across all random seeds
- Reduced test code by 56 lines while improving reliability
