refactor(tools): first-wave simplification of tools/ (file ops split, lazy_deps, code_exec, approval, browser, delegate, mcp, skills, terminal, voice, media)

Behavior-neutral structural pass over tools/*: god-file extractions into
sibling modules (file_operations_common/lint/search, file_tools_paths/
read_tracking/write, code_execution_env/rpc, tool_search_catalog/names/
validation, tts_command_provider, ...), duplicate helper unification,
if/elif -> dispatch tables, dead-code removal, docstring compaction.
Tool schemas (get_tool_definitions) verified byte-identical to base.

-
-Callers should import concrete submodules directly, for example:
-
-    import tools.web_tools
-    from tools import browser_tool
-
-Python will resolve those submodules via the package path without needing them
