- Extract JASPER_URL into a shared constants module
- Pass login credentials via a temp curl config file to avoid exposure
in the process argument list (ps/proc)
- Replace vim.ui.input secret prompt with vim.fn.inputsecret()
- Add -s (silent) flag to all curl calls to suppress progress output
- Guard curl output parser against missing newline in stdout
- Track per-activity shared timestamp file
(/tmp/jasper_<id>.last_activity)
so the inactivity watchdog skips auto-pause when another Neovim
instance is still active on the same task
- Clean up leftover uv_timer on repeated begin_tracking calls
- Remove shared activity file on teardown only when this instance wrote
it
