* harden

* fix red CI

* Refactor CodeMode to use CatalogTransform base class

Removes the duplicate ContextVar bypass pattern in favor of the shared
CatalogTransform machinery. Also fixes a pre-existing bug where
`from __future__ import annotations` caused NameError for Annotated
in nested function scopes at runtime.

* Remove redundant _get_visible_tools wrapper in CodeMode

* Rewrite CodeMode docs with proper motivation and structure

* Fix type narrowing in collision test

* Stop unwrapping tool results in CodeMode's call_tool

call_tool() inside execute blocks now returns structured content as-is,
preserving the {"result": value} wrapping. This means the output schema
shown in search results accurately describes what call_tool() returns,
so LLMs can trust the schema when writing code.

Also adds examples/code_mode/ with a server and narrated client demo.

* Simplify call_tool return type: dict | str

* Fix example client to unwrap structured results

* Let server resolve tool versions instead of pinning first match

* Rewrite CodeMode docs to match current behavior

* Rename optional extra from monty to code-mode

Experimental Tests

Each directory in this folder tests a discrete experimental feature. The directory structure within each experiment should approximate the "normal" test directory structure to facilitate moving tests into place once/if the experiment is merged into the main codebase.
