feat: migrate from Cedar to SpiceDB authorization system

This is a major architectural change that replaces the Cedar policy-based
authorization system with SpiceDB's relation-based authorization.

Key changes:

- Migrate from Rust to Go implementation
- Replace Cedar policies with SpiceDB schema and relationships
- Switch from envoy `ext_authz` with Cedar to SpiceDB permission checks
- Update build system and dependencies for Go ecosystem
- Maintain Envoy integration for external authorization

This change enables more flexible permission modeling through SpiceDB's
Google Zanzibar inspired relation-based system, supporting complex
hierarchical permissions that were difficult to express in Cedar.

Breaking change: Existing Cedar policies and Rust-based configuration
will no longer work and need to be migrated to SpiceDB schema.

-//! # `object`
-//!
-//! The `object` crate provides a unified interface to working with object files
-//! across platforms. It supports reading relocatable object files and executable files,
-//! and writing relocatable object files and some executable files.
-//!
-//! ## Raw struct definitions
-//!
-//! Raw structs are defined for: [ELF](elf), [Mach-O](macho), [PE/COFF](pe),
-//! [XCOFF](xcoff), [archive].
-//! Types and traits for zerocopy support are defined in the [`pod`] and [`endian`] modules.
-//!
-//! ## Unified read API
-//!
-//! The [`read`] module provides a unified read API using the [`read::Object`] trait.
-//! There is an implementation of this trait for [`read::File`], which allows reading any
-//! file format, as well as implementations for each file format.
-//!
-//! ## Low level read API
-//!
-//! The [`read#modules`] submodules define helpers that operate on the raw structs.
-//! These can be used instead of the unified API, or in conjunction with it to access
-//! details that are not available via the unified API.
-//!
-//! ## Unified write API
-//!
-//! The [`mod@write`] module provides a unified write API for relocatable object files
-//! using [`write::Object`]. This does not support writing executable files.
-//!
-//! ## Low level write API
-//!
-//! The [`mod@write#modules`] submodules define helpers for writing the raw structs.
-//!
-//! ## Build API
-//!
-//! The [`mod@build`] submodules define helpers for building object files, either from
-//! scratch or by modifying existing files.
-//!
-//! ## Shared definitions
-//!
-//! The crate provides a number of definitions that are used by both the read and write
-//! APIs. These are defined at the top level module, but none of these are the main entry
-//! points of the crate.
