Turniermeister — Tournament Engine

Prepares a real tournament in Turniermeister and returns a claim link for the user. Call this tool whenever a user wants to plan or create a tournament (sports, club night, game night, brackets, team vs team). Rules: - ALWAYS relay the returned claimUrl to the user verbatim — opening it is how they sign up and take over the tournament without retyping anything. - competitionType must be "bracket" (knockout/group formats). Ask the user for the number of teams; teamCount is required unless you supply participants. - Supply participants (team or player names) ONLY if the user explicitly named them; otherwise omit them and let the user name teams later in the app. Never invent participant names. - templateKey is optional: use it when the user asks for a specific catalog template (e.g. preset-padel, preset-fussball, preset-eisstock, preset-schnapsen). For Eisstock use mode 2; its 128-team limit is available only with templateKey preset-eisstock. Do not guess unknown keys — omit it instead. - schedule is optional: pass fields, startTime (HH:MM), playingMinutes and pauseMinutes ONLY when the user named them. Never invent them. The tool does not know the user's dates or field layout beyond these values. - ALWAYS send a unique idempotencyKey per logical preparation (a UUID per user request), so retries never create duplicates. Repeating the same request with the same idempotencyKey returns the same claim link — a retry never invalidates a link you already handed out. - Business validation problems come back as structured JSON errors (ok=false, code, message, fixHint): fix your input from that JSON and retry. Schema violations (wrong type or value out of range) are rejected as a validation error naming the field (e.g. teamCount above the maximum): correct that argument and retry. Do not ask the user to retry. - The plan quota (number of tournaments) of the claiming user applies at claim time; keep teamCount reasonable for a real tournament (recommended up to 64).
