Glossary result count is not announced when filtering #52

Context

#glossary-count has aria-live="polite" and its text is replaced on every keystroke. Updating a live region on every character produces a stream of interruptions, which in practice makes screen reader users turn it off or leave.

What to change

Files: js/glossary.js

Requirements:

• Debounce the announcement so it fires once the reader stops typing, not per character
• The visible count should still update immediately — only the announcement is debounced
• Roughly 300–500ms is the usual range; justify what you pick
• Do not remove the live region; the fix is timing, not deletion

Acceptance criteria

• The visible count updates instantly as you type
• The announcement fires once after typing stops
• Verified with a real screen reader
• Rapid typing does not queue up a backlog of announcements
