* studio: report the true reasoning duration and fix the Stop button for thinking models
For a local GGUF the "Thought for N" label was timed entirely on the client by a
brittle edge-detector, so an always-think model (Qwen3 MTP) that buffers its whole
reasoning and flushes it in one chunk showed "1 second" instead of the real
minute-plus. The client cannot time reasoning it receives atomically, so make the
timing backend-authoritative.
Backend: generate_chat_completion_with_tools measures wall-clock reasoning and
emits a Studio reasoning_summary event (duration_ms) at the moment reasoning ends
-- the first answer token, or end-of-stream for a reasoning-only reply -- for both
the tool-detection pass and the final-answer pass. Timing resets per tool
iteration so the final answer's thinking time wins on the client (which takes the
latest reasoning_summary). routes/inference.py forwards the event in the GGUF tool
stream.
Frontend: parse the reasoning_summary SSE into a _reasoningDurationMs chunk and
use it as the authoritative reasoning duration (last write wins), clamped to >= 0
and guarded to a finite number so a malformed or proxied chunk cannot produce a
NaN label; the persisted value wins for the final "Thought for N" label, with the
previous live timer kept only as a fallback when no metadata arrives.

* 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.

* Studio: Add inline confirmation (Allow/Always allow/Deny) for tool calls
* [pre-commit.ci] auto fixes from pre-commit.com hooks
for more information, see https://pre-commit.ci
* Fix race in tool-call confirmation gate
* Studio: gate built-in tool calls and harden the confirmation handshake
The Allow / Always allow / Deny controls only lived in the fallback tool
card, but the built-in tools (web search, python, terminal, code
execution, image generation) render with their own components and so
never showed the buttons. Those calls paused after tool_start with no way
to approve them, hanging until the 1 hour timeout. Only MCP tools, which
use the fallback renderer, actually worked.
Render the controls for every tool card by wrapping each registered tool
component (and the fallback) in thread.tsx with a shared
ToolConfirmationControls, so the gate applies uniformly.
Also make the handshake robust:
- The gate keys on a per-call approval_id minted by the backend and
echoed in tool_start, instead of session_id alone, so a stale or
concurrent confirmation can no longer resolve the wrong call.
- The approval slot is registered before tool_start is yielded, closing
the race where a fast click or an auto "Always allow" could reach the
backend before the waiter existed.
- The frontend resolves with the same session id the request was sent
with (plus the approval_id), fixing the new-thread mismatch where the
confirmation targeted a different session than the blocked stream.
- The confirm endpoint returns {resolved}; the UI keeps the buttons and
shows a retry hint until the backend confirms a match, instead of
hiding them on a failed or mistargeted post.
- The gate runs after the disabled-tool and duplicate-call checks, so a
call that will not execute is not put up for approval. A denied call is
still excluded from duplicate detection, so re-issuing and approving it
works.
- "Always allow" is scoped per session to match the backend gate.
Add backend tests for the approval registry, the SSE no-deadlock
handshake, and the loop integration (allow, deny, disabled, duplicate,
re-issue after deny).

* Studio: make the tool-call confirmation decision immutable
resolve_tool_decision accepted a second confirmation for the same approval_id
and overwrote slot["decision"] in the window before the waiter reads it and
pops the slot, so a duplicate or out-of-order POST could flip an Allow to Deny
(and returned a misleading resolved:true). Reject once the slot's event is
already set so the first decision wins. Adds a regression test.

Unify the Studio local tool-call loop (GGUF + safetensors) behind a shared ToolLoopController: ordered preface-then-tool-card rendering, duplicate-call de-looping with a forced final answer, XML-leak containment, and a parser fix that accepts closed <function=...> calls followed by trailing prose. Includes backend tests for the controller, strict parser, and GGUF route cursor reset.
