Changelog

1.2.0

BREAKING: Switch from "never overwrite" to "last wins" merge strategy
- .env values now override existing OS environment variables
- This matches the opencode-cli convention (local overrides user)
Add multi-location .env loading with cascading merge:
1. ~/.config/opencode/.env — global defaults (user email, shared API keys)
2. <projectDir>/.opencode/.env — project-specific overrides (wins)
Refactor loadEnvFile() → loadEnvFromPath() + loadMergedEnv() + getGlobalConfigDir()
Update AGENTS.md, README.md, and skill document with new behavior

Fix skills directory structure for plugin linker compatibility
- The linker expects skills/<group>/<skill-name>/ but the skill was at skills/<skill-name>/ directly
- The skill was silently never linked because the linker treated the skill directory as a group directory

Inject .env variables into process.env at plugin init time (Phase 1)
- Downstream plugins can now read .env values via process.env.KEY
- Eliminates the need for each plugin to implement its own .env parsing
Add shell-env-usage skill document
Add AGENTS.md with build commands and code style guidelines
Add GitHub Actions workflow for automated npm publishing on tag push
Move source code from plugins/ to src/ to avoid opencode-link symlinker collision
Extract loadEnvFile() helper function (DRY)
