[GeoGeekLab]

Summary

• add .geodebug.toml policy loading with profiles, rule disable, severity overrides, and reasoned suppressions
• add GEO103, GEO105, GEO301, GEO304, GEO502, and GEO503
• add operation-aware preflight() and geodebug preflight
• add deep Rasterio NoData/mask consistency scanning
• add CRS area-of-use facts and geographic bounds helpers
• add golden rule manifest with explicit must_not_report contracts
• document config and v0.1 rule behavior

Quality constraints

• policy never changes rule truth values
• expired suppressions do not enter runtime policy
• default checks remain metadata-first
• deep raster scans are explicit
• area-of-use diagnostics are limited to projected CRS to avoid cascading geographic-range findings
