Capture bar shows inline pills as you type — glyph, title, desc,
tags, time, pin, card type. Textarea auto-grows on Shift+Enter.
Preview clears on save. Entity list rows now show description.
Kind prefixes now follow the canonical grammar: `-` for todo,
`@time` for event, `!time` for reminder. Removed `*`/`◇`/`▸`
as capture aliases (display-layer only). Added `\` escape prefix,
`?` query mode, `!pin` flag extraction, `##word` hash escape,
and tag lowercasing. Both parsers produce identical results.
