efuse_pkg

Define shared eFuse field-map rules, shadow range maps, and bus typedef helpers.

Provides rule_t, shadow_word_range_map_t, and related constants imported by the controller, guard, shadow regs, and token processing. Also defines the lifecycle-state encoding, fuse commands, and address-decode selects, and includes the AXI, APB, and fuse-command typedef macros used by interface blocks.
