fix(parser): align Go and JS parsers with capture grammar spec

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.
