refactor(cli): align question gating with upstream position

Move the Kilo question-tool boolean adjacent to `const cfg = yield* config.get()`
matching upstream's placement (commit 9d3c81a68, right after `const config = await
Config.get()`). When upstream's version eventually merges in, the two lines land
next to each other and produce a localized textual conflict — instead of silently
coexisting as dead upstream code plus our divergent gating.

Rename `const question = yield* QuestionTool` to `questiontool` (matching our
existing `lsptool`/`suggesttool` pattern) so the `question` identifier is free
for the boolean, aligning exactly with upstream's naming.
