fix(lint-org): stop flagging session anchors with todo.org conventions

The todo-format checkers encode todo.org's completion rules, so they misfired on a session anchor. A Session Log's dated level-2 headings are the documented correct form, and every one came back as a defect telling the author to convert it to DONE plus CLOSED. One 427-line anchor produced six.

lo--spec-file-p becomes lo--todo-format-exempt-p. It now covers the live anchor, the per-agent anchors, and the archives alongside docs/specs/. The archives belong there because wrap-up renames the anchor unchanged, so it keeps the same shape later in its life.

All five checkers in the family fire on an anchor, not only the dated-header one. Link, table and structural checks still run.
