Anthbot Map v2.4.7.3

• Improves live-map performance by coalescing bursty coordinator updates before WebSocket publication.
• Moves snapshot/delta construction work out of the Home Assistant event loop and uses immutable path frames so a growing trajectory cannot produce torn live-map updates.
• Keeps reconnect/full-snapshot continuity and the existing absolute-index live-path handling intact.
• Includes the latest Genie live-path/progress presentation hardening, M-series progress post-trim handling, stationary-position handling, and location-recorder hardening from the tested 2.4.7.2 live-map performance line.
• Preserves the v2.4.7.2 startup-safe developer-agent lifecycle and cloud/API resilience fixes.
• Updates stale regression expectations to the current control router, diagnostics attributes, and M-series stop_all_tasks payload without changing production command routing.
• Full validation before release: 359/359 unit tests passed, plus Python compilation and live-map targeted checks.
• Repository cleanup: version-specific CHANGELOG_v*.md and RELEASE_NOTES_v*.md files are removed. Release history is consolidated here and GitHub Releases retain the published historical notes.
