v0.3.0: rename app Daybook -> AgentFeed

Removes the "Daybook" name from everything user- and agent-facing, since no
agents are configured yet and this is the cheap moment to do it.

- UI brand, docs, README, CLAUDE.md -> AgentFeed.
- Ingest env vars DAYBOOK_URL/TOKEN/SOURCE/DATA_DIR/BIND_ADDR/HOST_DATA_DIR/
  KEY_PROVISIONING_API -> AGENTFEED_* (token *values* unchanged).
- Skill: skills/daybook-posting -> skills/agentfeed-posting, daybook_post.py
  -> agentfeed_post.py (+ scripts/ wrapper and its test).
- static/daybook.css -> static/agentfeed.css; localStorage daybook.* ->
  agentfeed.*; templatetag daybook_extras -> agentfeed_extras; multipart
  boundaries; json/csv viewer element ids; daybook_exception_handler ->
  agentfeed_exception_handler; compose service/container -> agentfeed.
- Key-provisioning API now OFF by default (independent of DEBUG); enable with
  AGENTFEED_KEY_PROVISIONING_API=1 on test installs only.
- Posting helper now points at Settings -> API Keys.

Deferred on purpose (a later, separate step): the Django package
`daybook_project`, the `/opt/daybook` install path, and the Forgejo repo name.
The sibling AGENT_DAYBOOK__LLM_TEST name is intentionally untouched.

Full suite: 129 passing; live server verified serving under the new name.
