Paired-release commit that completes the .notify migration started in
opencode-ruby v0.0.1.alpha2.
Changes:
- lib/opencode/exchange.rb: drops the empty '{ }' block from the
apply_patch.artifacts_dropped emission, switching from
.instrument(...) { } to .notify(...). Identical wire semantics,
cleaner read at the call site.
- opencode-rails.gemspec: pins opencode-ruby runtime dep to
'= 0.0.1.alpha2' (was alpha1). Lockstep versions during alpha.
- lib/opencode/rails_version.rb: 0.0.1.alpha1 -> 0.0.1.alpha2.
- CHANGELOG: documents the Exchange call-site change and the
opencode-ruby pin bump.
