feat(workspace): add full-text search for daily memory files

Add backend search command that performs case-insensitive matching
across all daily memory files, supporting both date and content queries.
Frontend includes animated search bar (⌘F), debounced input, snippet
display with match count badge, and search state preservation across
edits.
