Tool contract 11.16.0

Timeline lines read as a person says them, in one wording for every door, and an occurred clan entry's activity counts every battle played in the window.

• elixir_timeline, players_timeline, clans_timeline, clans_members_timeline: text changes. A sitting is "played 10 battles in one sitting", a race "finished Season 137, week 4 (Colosseum) in 2nd place", a clan summary says departed: for left: and sittings for sessions, modes read Path of Legends and Casual. Read facts, never parse text. Stored keys and kinds are unchanged.
• A clan entry's roster.left[] no longer serves tenure_days: how long someone stayed is not part of a departure's record of the week.
• departure_classified: new optional facts.role_at_departure, read from the membership; the sentence ends "(was Member)" when it is known.
• A clan entry's activity on an occurred read counts battles played in [from, to) by battle_time, including ones learned late. Boat defenses are out on both bases.

JSON API unchanged. clans_participation is unchanged and its week columns stay ISO weeks.
