3 core dberror type definition

[lxsaah]

Added

• Unified error handling system for all AimDB platforms (MCU → Edge → Cloud) with conditional compilation support. ([Core DbError Type Definition #3])
• DbError enum in aimdb-core/src/error.rs with comprehensive error taxonomies covering Network, Capacity, Serialization, Configuration, Resource, and Hardware scenarios. ([Core DbError Type Definition #3])
• DbResult type alias exported from aimdb-core for consistent error handling across all components. ([Core DbError Type Definition #3])
• Cross-platform error optimization with memory-efficient implementations:
  • 24 bytes in no_std mode for MCU/embedded targets
  • 56 bytes in std mode for edge/cloud environments
  • Both implementations stay well under the 64-byte embedded constraint. ([Core DbError Type Definition #3])
• Platform-specific error helper methods including network_timeout(), capacity_exceeded(), hardware_error(), and internal() constructors. ([Core DbError Type Definition #3])
• Error categorization methods (is_network_error(), is_capacity_error(), is_hardware_error()) for semantic error handling. ([Core DbError Type Definition #3])
• Comprehensive documentation with usage examples for MCU, edge, and cloud deployment scenarios. ([Core DbError Type Definition #3])
• Feature flag support with std (default) and no_std modes for optimal platform targeting. ([Core DbError Type Definition #3])
• Cross-platform testing suite validating error functionality across both std and no_std environments. ([Core DbError Type Definition #3])

Changed

• Updated workspace thiserror dependency from version 1.0 to 2.0.16 for improved error handling capabilities.
• Enhanced aimdb-core module structure with proper API exports and comprehensive crate documentation.
• Replaced placeholder code in aimdb-core with production-ready error handling foundation.

Dependencies

• Added thiserror 2.0.16 as optional dependency for std feature flag support
• Added heapless 0.9.1 as development dependency for no_std testing capabilities

---

Notes:

• [Core DbError Type Definition #3]: Core DbError Type Definition - Core DbError Type Definition #3
• This release establishes the foundational error handling system for the entire AimDB ecosystem
• All error variants compile successfully on both std and no_std targets
• Memory constraints verified: 24 bytes (no_std) and 56 bytes (std) both ≤ 64-byte embedded limit

Magic numbers in comments should be defined as constants to improve maintainability and prevent inconsistencies. Consider creating an enum or constants like const FORMAT_JSON: u8 = 0; for these format identifiers.

Similar to the format field, these resource type magic numbers should be defined as constants or an enum to improve code clarity and prevent errors when matching against these values.
