core: consolidate shared infrastructure into core package

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.
