feat: add granular heading/block selection for context

- Add ContentSelector for parsing heading structure via metadataCache
- Support reference syntax: NoteName#Heading and NoteName^blockid
- Add FileSelectorModal with expandable heading tree and checkboxes
- Live token counter updates as sections are selected/deselected
- New command: "Copy context (select sections)"
- Add "Select Sections..." button in generator modal
- Mark partially selected files with "(partial)" suffix
- Cascading selection: toggling parent affects all children
