With the zero-tools transition complete, the tools/builtin/ package
served no purpose — Builtins() returned nil. Removed:
- tools/builtin/builtins.go and the directory
- builtins field, WithBuiltins, Dispatch from toolsrv.Server
- Handler type from toolsrv (only used by builtins)
- OnPreDispatch/WithOnPreDispatch (dead code)
- Strict field and WithStrict (dead code, never read)
- CallTool simplified — no fallback to Dispatch
- builtin import and WithBuiltins/WithStrict calls from ollie-remote
- tools/builtin from justfile build/test targets
Updated AGENTS.md, ARCHITECTURE.md, README.md, EVOLUTION.md
