Implements the complete Phase A (Linux-hosted) RuVix Cognition Kernel
with 9 crates, 760 tests, and comprehensive documentation.

## Core Crates (9)
- ruvix-types: 6 kernel primitives (Task, Capability, Region, Queue, Timer, Proof)
- ruvix-cap: seL4-inspired capability management with derivation trees
- ruvix-region: Memory regions (Immutable, AppendOnly, Slab policies)
- ruvix-queue: io_uring-style lock-free IPC with zero-copy semantics
- ruvix-proof: 3-tier proof engine (Reflex <100ns, Standard <100us, Deep <10ms)
- ruvix-sched: Coherence-aware scheduler with priority computation
- ruvix-boot: 5-stage RVF boot loader with ML-DSA-65 signatures
- ruvix-vecgraph: Kernel-resident vector/graph stores with HNSW
- ruvix-nucleus: Unified kernel entry point with 12 syscalls

## Security (SEC-001, SEC-002)
- Boot signature failure: PANIC immediately, no fallback path
- Proof cache: 100ms TTL, single-use nonces, max 64 entries
- Capability delegation depth: max 8 levels with audit warnings

## Architecture
- no_std compatible for Phase B bare metal port
- Proof-gated mutation: every state change requires cryptographic proof
- Capability-based access control: no syscall without valid capability
- Zero-copy IPC via region descriptors (TOCTOU protected)

## Documentation
- Main README with architecture diagrams
- Individual crate READMEs with usage examples
- Architecture decision records

- Update ADR-087 status from Proposed to Accepted (Phase A Implemented)
- Add implementation status table with all 9 crates and 760 tests
- Document security invariants implemented (SEC-001 through SEC-004)
- Add collapsed RuVix section to root README with architecture diagram

… CVE-005

Security fixes applied from deep review audit:

- CVE-001 (CRITICAL): Add compile-time protection preventing
  `disable-boot-verify` feature in release builds. This closes
  a boot signature bypass vulnerability.

- CVE-002 (HIGH): Add MMIO address validation to GIC driver.
  `Gic::new()` now returns `Result<Self, GicError>` and validates
  addresses against known platform ranges. Added `new_unchecked()`
  for trusted callers.

- CVE-003 (HIGH): Add integer overflow protection in DTB parser.
  All offset calculations now use `checked_add()` to prevent
  buffer overflow via crafted DTB files.

- CVE-005 (HIGH): Add IPv4 header validation ensuring
  `total_length >= header_len` per RFC 791.

Also includes test fixes:
- Mark hardware-dependent tests as `#[ignore]` (MMIO, ARM timer)
- Fix swap32 test assertion in rpi-boot
- Update doctests for new GIC API

All 259 tests pass across affected crates.
