Queued messages tag monitor output, and remembered reads report how many were dropped

What

Queued messages are messages waiting to be handed to Claude, such as output from a monitor that watches something running in the background.

• A queued message tied to a watch now carries monitorEvent, holding the watch id and a kind: "notice" for housekeeping messages and "output" otherwise.
• The record of a delivered queued message gains monitor_event_count and monitor_event_chars.
• The helper that limits how many remembered file reads are kept no longer logs remembered_read_dropped itself. It now returns the kept reads together with a count of how many were dropped. One finding reports dropped reads still being logged under that name, so the logging appears to have moved to the code that calls the helper.
• Home-seed announcements now record how late the read was.

Why

Monitor output can now be told apart from other messages slipped into the conversation. Most of the rest changes what is measured rather than what you see.
