Phase 5 t5.2 partial: applied adaptation 1 from spec §6 to
render_files_and_media (src/gui_2.py:3030).
The 'Add Screenshots' button is now disabled when the active model's
capability matrix has vision=False. A tooltip-adjacent text_disabled
note shows '(vision not supported by <model>; attachments would be
ignored)' so the user knows WHY the button is disabled.
Pattern established for the remaining 8 adaptations (t5.2.2 through
t5.2.9 per spec §6):
caps = app._get_active_capabilities()
imgui.begin_disabled(not caps.<field>)
... UI ...
imgui.end_disabled()
if not caps.<field>:
imgui.same_line()
imgui.text_disabled('(reason)')
The remaining 8 adaptations (tools toggle, cache panel, stream
progress, fetch models, token budget, cost panel x3) are deferred to
a follow-up track. The pattern is established; the work is
mechanical application of it.
38/38 regression tests still pass; no behavioral change beyond the
adaptation 1 wrapping.
