Moves effect logging, observability, runtime utilities, flags, installation
version info, and process utilities from opencode to core package. This
enables better code sharing across packages and establishes core as the
single source of truth for foundational utilities.
All internal imports updated to use @opencode-ai/core paths for consistency.
Config is now loaded eagerly during project bootstrap so users can see config loading in traces during startup. This helps diagnose configuration issues earlier in the initialization flow.
NPM installation logic has been refactored with a unified reify function and improved InstallFailedError that includes both the packages being installed and the target directory. This provides users with complete context when package installations fail, making it easier to identify which dependency or project directory caused the issue.
