Calls execute_tool_block through the live src.tool_execution module in the edit-file admin-gate test so the monkeypatched _owner_is_admin seam and the called function belong to the same module object. Fixes the scoped #2580 CI-order edit-file failure. Remaining Python failure is the unrelated cookbook fallback-chain environment test.
* Add edit_file tool + file-change diffs
edit_file is an exact old_string -> new_string replacement on a file on disk
(fails if old_string is missing or non-unique unless replace_all); write_file
also returns a unified diff. Diffs render collapsed in the tool bubble
(filename + +adds/-dels, theme colors); the raw JSON command box is hidden.
Security: edit_file is a sensitive filesystem-write tool, treated everywhere
write_file is —
- added to NON_ADMIN_BLOCKED_TOOLS (is_public_blocked_tool / blocked_tools_for_owner),
so on auth-enabled deployments a non-admin cannot run it; execute_tool_block
refuses it for non-admin owners.
- confined by the same path policy as read_file/write_file (allowlist +
sensitive-file deny) via _resolve_tool_path.
Disambiguation in tool descriptions + bash prompt: edit_file/write_file are the
only way to write files (they show a diff) — never edit_document (editor panel)
or a bash heredoc/redirect.
Tests (tests/test_edit_file.py): non-admin block (policy + execution gate),
successful edit, not-found old_string, non-unique old_string (+ replace_all),
and path outside the allowed roots.

* Drop redundant import os in write_file closure
os is already imported at module top.
