fix(dankvoice): pin thinking off in rewrite, fix silent and timeout modes

Refs #32

The humanizer's raw fetch to frank-zealot omitted
chat_template_kwargs.enable_thinking: false, so the Qwen35 hybrid thought
instead of answering (6.9 s reasoning_content, empty content - timing out
the 6 s abort; or answering "" and muting the unit). Pin the kwarg, treat
empty-content-with-reasoning as failure over silence, and stop the menu's
test phrase from blocking its handler. Three red-captured regressions;
26/26 green, verified red against HEAD.

+The humanizer's raw `fetch` to frank-zealot omitted `chat_template_kwargs.
+enable_thinking: false`, so the Qwen35 hybrid *thought* instead of answering:
+6.9 s of `reasoning_content`, `content: ""` — timing out the rewrite twice
+(12 s dead air) and, when it did answer inside the window, speaking silence.
+Root-caused by replaying the exact wire body against the live endpoint.
+Fix: pin the kwarg in the request body; treat empty-content-with-reasoning as
+failure (mechanical voice), not "nothing worth saying"; the menu's test phrase
+fires without blocking its handler. Lesson: the harness injects thinking-off
+for managed roles, but raw HTTP callers must set it themselves — 26/26 green
+with three red-captured regressions.
