* Studio: show tool-call progress for large GGUF tool arguments
The GGUF agentic tool loop only surfaced an early provisional tool card
for render_html, so any other tool (python, terminal, ...) was invisible
in the UI while its arguments streamed. For a large argument such as a
full HTML or code file this left the chat sitting on "Generating..." with
zero progress for tens of seconds while the model was clearly working.
Generalize the provisional tool_start to any enabled tool once its
streamed arguments grow past a threshold (render_html still surfaces
immediately, small-argument tools are unchanged). The provisional and the
real tool_start share the tool_call_id so the frontend reconciles them
into one card. Close the provisional on no-op, denial, parallel-drop,
post-loop, and on stream errors so a card can never spin forever, surface
each parallel call, and skip the early card while a human confirmation
gate is active. Apply the same confirmation-gate guard to the safetensors
agentic loop.
Additional hardening:
- Only emit a provisional card once a real, non-empty tool_call_id is
known. llama.cpp can stream a tool call with an empty id, and a card
keyed by "" cannot reconcile with the real tool_start (the frontend
mints its own id per event), so it would dangle.
- On a connection drop or other mid-iteration failure, close the dangling
provisional card with an error result instead of an empty success so the
UI renders it as failed rather than completed.
- Mirror the provisional cleanup in the safetensors loop: close a
provisional render_html card if the model generator raises mid-stream or
the controller turns the call into an internal no-op.
Adds regression tests for the empty-id guard, the error-result on a
dropped connection, and the safetensors mid-stream exception cleanup.
