Subject: [PATCH] fix: date-based digest URLs, social link, and tag separators
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Add GetDigestByDate and support ?date=YYYY-MM-DD in digest handler
- Social digest thread now links to /news/digest?date=ID instead of /news
- Tags in blog listings and post pages separated by · instead of spaces
