feat(setup): wizard prompt tweaks and quieter query-history filter output (#259)

Setup wizard flow tweaks:
- Add a reveal-tail password prompt (reveal-password-prompt.ts) that unmasks
  the last few characters of a typed/pasted secret, and wire it into the setup
  prompt adapter in place of clack's password(); adds the @clack/core dep.
- Reorder wizard select options: surface "Paste a key" before the
  environment-variable option across embeddings/models/sources, promote
  Metabase/Notion in the source list, put Git URL before Local path, reorder
  the Notion crawl-mode choices, and relabel the sources "Done" action.

Query-history filter picker output:
- Collapse the per-template parse-failure lines into a single count in the
  setup output and route the full template-id list to --debug stderr.
- Model parse failures as a structured parseFailedTemplateIds field instead of
  warning strings.
- Add a privacy-safe query_history_filter_completed telemetry event
  (counts/enums only), mirrored into the Python daemon schema.
