- Migrated all environment variable access from Node.js `process.env` to Bun runtime `Bun.env` API across the entire codebase. - Updated 71 files including source code, tests, documentation, and configuration to use Bun's native environment variable API. - Added comprehensive environment variables documentation in `packages/coding-agent/docs/environment-variables.md` covering 100+ environment variables organized by category. - Updated CHANGELOG entries to reflect migration from `process.env` to `Bun.env` and environment variable prefix changes (PI_* vs OMP_*). - Maintained identical behavior and logic across all changes - only the environment variable access method was updated.
