In release builds with SEGMENT_WRITE_KEY baked in (i.e. CI), the
post-command telemetry flush calls spawn_fabro_subcommand, which in turn
does create_dir_all(~/.fabro/tmp) and writes a JSONL event file. That
silently undoes the directory removal that `fabro uninstall --yes` just
performed — leaving a stray ~/.fabro/tmp/ behind and breaking the
uninstall integration tests on CI release runs.
Fixes:
- run_uninstall calls fabro_telemetry::shutdown() before removal so the
buffered "CLI Executed" track in main() can't be queued or flushed,
and the background thread can't spawn the sender subprocess.
- TestContext::command() exports FABRO_TELEMETRY=off so test subprocesses
never initialise telemetry at all, as a belt-and-suspenders guard.
