Merge remote-tracking branch 'upstream/dev' into feat/space-invite-share

## Summary

This PR fixes a bug where deleting a room succeeded on the relay, but the room could still appear in space navigation (including after refresh).

Fixes #194.

## Root Cause

Room list derivation did not consistently treat delete events as authoritative in edge cases:
- Delete timestamp aggregation could involve an undefined prior value.
- Room meta events with the same second-level timestamp as a delete event were still considered active.

## Changes

- Updated room delete timestamp aggregation logic to handle first delete event safely.
- Updated room filtering condition so a room is excluded when its meta timestamp is less than or equal to the delete timestamp.
- This ensures deleted rooms are not shown in navigation immediately or after reload.

## Validation

- `pnpm run check` passed.
- `pnpm run lint` passed.

## Testing

- [x] In a NIP-29 space, create a temporary room.
- [x] Delete the room from room details.
- [x] Confirm it disappears from navigation immediately.
- [x] Hard refresh and confirm it does not reappear.
- [x] Reopen app/session and confirm it remains absent.
- [x] Repeat by creating/deleting another room quickly (same-minute timestamp edge case).
