feat(bins): multi-library populate_knowledge + progress UX

populate_knowledge now loads real libraries from the DB instead of
fabricating a single library_id=1 row from BASE_PATH. Adds --library
<id|name> to restrict the walk and validates --path against the selected
library roots. The full library set is still passed to InsightGenerator so
resolve_full_path can probe every root when an insight resolves to a
different library than the one being walked.

Adds indicatif progress bars across the long-running utility binaries via
a shared src/bin_progress.rs helper (determinate bar + open-ended spinner
with consistent styling). Per-batch info! noise is replaced by the bar's
throughput/ETA; warnings and errors route through pb.println so they
scroll above the bar instead of fighting with it.

  populate_knowledge   spinner during scan, determinate bar over all libs
  backfill_hashes      spinner with running hashed/missing/errors counts
  import_calendar      determinate bar; embedding/store failures inline
  import_location_*    determinate bar advancing by chunk size
  import_search_*      determinate bar; pb cloned into the spawn task
  cleanup_files P1     determinate bar over DB paths
  cleanup_files P2     determinate bar; pb.suspend() around y/n/a/s prompt
