1.5.0

Added

• An "Add person" button in the dashboard header, and the same dialog offered
  from the empty states — previously creating a person was only reachable through
  the command palette, which is easy to miss.
• The dialog asks for the tier alongside the name. A person with no tier isn't
  tracked at all, so creating one without asking would quietly produce someone the
  plugin ignores.

Performance

• Exclusion fragments are tokenized once per index build instead of once per
  candidate file, so the cost no longer scales with files × fragments. Measured on
  5,000 people: 20 fragments went from 20.8ms to 13.7ms, and the cost is now flat in
  fragment count rather than linear.
• A file already inside a people folder no longer has its tags and type marker
  evaluated, since neither can change the outcome. Tag-based identification across
  13,000 files: 5.2ms to 4.4ms.
• The unrendered-placeholder check does a cheap substring test before its regex,
  which almost never matches.
