Subject: [PATCH 28/77] refactor(agent/image+safety): route vision
probes/inline executors on data tables, dedupe path guards (-25% LOC)
- image_routing: capability probes -> _VISION_PROBES ordered table; magic-byte
sniffing -> _MAGIC signature table; bool tokens -> dict; shared code-span /
file-existence helpers for extract_image_refs. Fixture-corpus diff base vs
new identical.
- inline_tool_executors: 11 hand-written executor bodies -> _tool/_callback_tool
arg-spec factories (kwargs mapping unchanged; corpus of calls identical).
- file_safety: unify _is_under/_under_any, _resolve_target/_resolve_each,
_mirror_info; deny-list tables compacted; drop retired
get_cross_profile_warning stub (+ its tests). Every rule preserved (corpus).
- image_gen_provider: drop _images_cache_dir (test-only wrapper), compact.
- estop/delegation_context/kanban_stop/image_gen_registry: defensive-layer
collapse and docstring compaction.
Tool schema dump byte-identical to base.

"""Routing helpers for inbound user-attached images.

- text — run ``vision_analyze`` on each image up-front and prepend the

-plus the active model's capability metadata. In ``auto`` mode:
-
- - An explicitly configured ``auxiliary.vision`` backend is the DE-FACTO route
- (``text``): a user who named a dedicated vision model wants it used even
- when the main model has native vision. ``image_input_mode: native`` is the
- absolute override.
- - Otherwise, ``supports_vision=True`` (config override or catalog) → native.
- - Otherwise text via the default vision_analyze flow.
-
-``vision_analyze`` stays surfaced as a tool in every session so skills that
