Initilaized project complete Phase 0 foundation — workspace, types, schema, error hierarchy, storage trait, test harness, CI

- Rust workspace with aegis-core + aegis-test-utils crates
- Core types: SubjectId, ResourceId, Relation (validated newtypes with injection prevention)
- Data model: RelationshipTuple, Revision, RevisionToken, ConsistencyMode, Schema, TupleKey
- Error hierarchy: AegisError with 20+ variants across 6 categories
- Schema parser + linter: YAML parser, orphan detection, circular inheritance check, compatibility checker
- StorageBackend trait (15 methods) + StorageTransaction trait + full filter/pagination types
- TestAegis in-memory engine with write/check/delete/list/query/pagination + fixture loader
- 4 built-in test fixtures (basic-team, multi-tenant, deep-hierarchy, circular)
- GitHub Actions CI: format, clippy, test (debug+release), coverage, security audit
- Updated aegis-spec.md (1982 lines, adds 5 new sections, fixes all inconsistencies)
- aegis-test-plan.md (567 lines, 180 test cases across 12 categories)
- IMPLEMENTATION.md (36 KB, 25 sprints across 4 phases with full dependency graph)
- .gitignore for Rust/IDE/OS artifacts
89 tests passing across both crates, 0 warnings, 0 errors.
