Subject: 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.

-# generic-array
-
-This crate implements generic array types for Rust.
-
-**Requires minumum Rust version of 1.36.0, or 1.41.0 for `From<[T; N]>` implementations**
-
-[Documentation](http://fizyk20.github.io/generic-array/generic_array/)
-
-## Usage
-
-The Rust arrays `[T; N]` are problematic in that they can't be used generically with respect to `N`, so for example this won't work:
-
-```rust
-struct Foo<N> {
-	data: [i32; N]
-}
-```
-
-**generic-array** defines a new trait `ArrayLength<T>` and a struct `GenericArray<T, N: ArrayLength<T>>`, which let the above be implemented as:
-
-```rust
-struct Foo<N: ArrayLength<i32>> {
-	data: GenericArray<i32, N>
-}
-```
-
-The `ArrayLength<T>` trait is implemented by default for [unsigned integer types](http://fizyk20.github.io/generic-array/typenum/uint/index.html) from [typenum](http://fizyk20.github.io/generic-array/typenum/index.html) crate:
-
-```rust
-use generic_array::typenum::U5;
-
-struct Foo<N: ArrayLength<i32>> {
-    data: GenericArray<i32, N>
-}
-
-fn main() {
-    let foo = Foo::<U5>{data: GenericArray::default()};
-}
-```
-
-For example, `GenericArray<T, U5>` would work almost like `[T; 5]`:
-
-```rust
-use generic_array::typenum::U5;
-
-struct Foo<T, N: ArrayLength<T>> {
-    data: GenericArray<T, N>
-}
-
-fn main() {
-    let foo = Foo::<i32, U5>{data: GenericArray::default()};
-}
-```
-
-In version 0.1.1 an `arr!` macro was introduced, allowing for creation of arrays as shown below:
-
-```rust
-let array = arr![u32; 1, 2, 3];
-assert_eq!(array[2], 3);
-```
