v0.2.3

Bug Fixes

• P1-1: report create no longer fails on valid API responses with timestamp: null or broadcasted_at as string
• P1-2: report list no longer rejects anonymous reports (member omitted) or reports with answer: null
• P1-3: standup replace carries forward time, days, timezone, users, and wait_time from previous state instead of resetting to defaults
• P2-1: wait_time=-1 (exact-time mode) is preserved through normalization and accepted by --wait-time validation
• P2-2: Undo receipts now include --users flag and correctly handle wait_time values of 0 and -1
• P2-3: standup start --users with a non-member user now shows a targeted error instead of suggesting wrong standup IDs
• P2-4: Whitespace-only --api-key or GEEKBOT_API_KEY falls through to the next auth source instead of sending empty credentials
• P3-1: Date filter help text now says "YYYY-MM-DD" instead of "ISO 8601" to match actual parser behavior
• P3-2: standup list --brief now includes all 6 documented fields (id, name, channel, time, timezone, days)
