Rolling out to #Pachli Current now:

- Long-press links, hashtags, and mentions to open the "share sheet"
- Better UI when writing media captions
- #Accessibility fixes:
. "Open boost author" works as intended
. Include a "Copy" button for links/hashtags/mentions in dialogs
. Show links/hashtags/mentions options in notifications
. Use checkboxes when managing list membership

Most of these were from user feedback. Thanks to everyone who took the time to provide it.
