Anthbot Map v2.4.8.2

• Adds an isolated Pion / MGC model family and recognizes cloud model identifiers such as MGC500, MGC750 and MGC1000 instead of routing them through Genie-only behavior.
• Normalizes the confirmed flat MGC shadow fields without changing their raw vendor values, including cutting height, mowing progress/area, mowing direction, rain status, RSSI/IP, map revision, current path payload, breakpoint and board firmware data.
• Fixes Pion/MGC native weekly schedules where week: 1..7 is a single weekday rather than a Genie-style bitmask.
• Preserves the MGC app schedule shape: one native appointment per weekday, full-lawn work mode, top-level cutting height fallback and the existing full value envelope instead of assuming the M-series incremental schedule payload.
• Uses the native Pion/MGC cloud wake/start path and avoids the Genie-only app_state preamble before mow_start.
• Exposes confirmed MGC cutting-height, mowing-progress and mapped-area values through the existing Home Assistant sensors using a Pion-only namespaced fallback.
• Keeps Genie, M5/M9/M9 Pro and N8 model guards unchanged and adds dedicated regression coverage for Pion/MGC isolation.
• Does not enable guessed Pion/MGC rain/cutting-height write payloads or a guessed curpath decoder; those remain disabled until the app/real hardware confirms their exact protocol.
