Anthbot Map v2.4.6-beta.11

N8 validation prerelease based on release/v2.4.6-beta.9.

Added

Initial isolated ANTHBOT N8 / MGS03 model-family support.
N8-specific command transport using the native app-style service-shadow flow.
Full-area mowing, pause, resume, stop and return-to-dock routing for N8 without the Genie app_state preamble.
Existing manual-zone and auto-zone mowing command routing for N8.
N8 map-manager archive support with area_setting.json zone extraction using the proven MGS decoders.
N8 mowing-path adapter.
N8-specific status and history normalization.
N8 rain payload normalization.
N8 Start grass dumping and Stop grass dumping button entities.
N8 dumping/grass hardware sensors.
N8 mowing work-mode selector.
N8 anti-loss switch.

N8 support is implemented through separate N8 adapters and explicit model boundaries.
Genie, M5, M9 and M9 Pro routing remains protected by regression coverage.
This prerelease is intentionally based on v2.4.6-beta.9; the separate release/v2.4.6-beta.10 test branch is not included or modified.

GitHub Validate workflow passes on the N8 feature head before this release branch was created.
Regression coverage includes N8 routing, map/zone isolation, mowing path, status/history, rain normalization, N8-only sensors, work mode and anti-loss controls.

The following N8 functions remain disabled until their live payload behavior is validated or the remaining protocol work is complete:

This is a prerelease intended for live N8 owner testing before the N8 support is merged into the normal release line.
