Instead of setting context = events (which made repliesByParentId always
empty), query the repository for events that #e-tag our matched event
IDs with kinds NOTE, COMMENT, or REACTION. This gives buildParameters
real reply/reaction data to count.
Fixes the bug where every event in the digest email showed
'0 replies / 0 reactions'.
Added test/digest-reply-stats.test.ts that:
- Publishes reply and reaction events into a mock repository
- Calls sendFromStoredEvents with only the parent event
- Asserts that the resulting digest parameters show Replies >= 1 and
Reactions >= 1
The buildParameters function returns events sorted newest-first
(sortBy created_at, slice(0,100)), and the mjml section is already
labeled 'Latest Activity'. The object keys Popular/HasPopular no
longer reflect the semantics, so rename them to Latest/HasLatest.
Resolve 21 pre-existing @typescript-eslint/no-unused-vars errors across
5 files (actions.ts, alert.ts, digest.ts, env.ts, worker/email.ts) that
were blocking the script/checks gate. All removals are unused imports
and unused variable assignments with no runtime impact.
