Since we can't mutate NdbNotes, let's update the existing codebase to
generate and sign ids on NostrEvent constructions. This will allow us to
match NdbNote's constructor
This adds post composition tests so that we can avoid composition bugs.
This still does not capture all of the dynamics of post composition,
because it ignores much of the mutable cursor position and related state
when editing posts.
We will need to make post editing more pure and less mutable in the
future to get test coverage on those.
Switch the post parser to use the same code as the content parser. This
was causing many issues, including performance issues.
Changelog-Fixed: Fix lag when creating large posts
Changelog-Fixed: Fix npub mentions failing to parse in some cases
Changelog-Added: Add r tag when mentioning a url
Changelog-Removed: Remove old @ and & hex key mentions
This is needed for longform events. Right now we treat unseparated note
artifacts as a list of blocks, but we will likely need to render these
blocks into lists of attributed texts with image blocks inbetween.
You can now use @npub, @note or @nsec to reference notes and pubkeys
Changelog-Changed: use bech32 ids everywhere
