docs(plugins): restore the telemetry sweep this branch's merge reverted

The pr4 -> pr5 merge resolved eleven documentation files to the pre-sweep
side, undoing aa770aa6 in its entirety. Because the stack lands in order,
main would have taken the corrected wording in pr1 and then had it reverted
by pr5, leaving the shipped claim wrong again:

- all six hosts' pause skill back to "a minimal anonymous telemetry ping"
- docs/integrations/deepseek-plugin.mdx back to "Anonymous usage events"
- integrations/zapier-mem0/README.md back to advertising telemetry the app
  does not have, with an MEM0_TELEMETRY opt-out that controls nothing
- the README data-dir listing back to omitting telemetry-salt and
  install-state.json, both of which this stack creates
- the README and docs property lists back to the enumeration that drifts

Restored verbatim from pr4. No file here is in pr5's scope, and the full
pr4..pr5 diff is now surface headers only.
