feat(v0.2): Complete v0.2 Feature Set - 7 New Rust Modules

[m96-chan]

Summary

This PR completes the PyGPUkit v0.2 feature set with 7 new Rust modules and comprehensive PyO3 bindings.

New Rust Core Modules (7276 lines)

Module	Description
scheduler/admission.rs	Deterministic admission control with memory/bandwidth quotas
scheduler/qos.rs	QoS policy framework (Guaranteed/Burstable/BestEffort tiers)
scheduler/partition.rs	GPU resource partitioning for multi-tenant isolation
dispatch/pacing.rs	Kernel pacing engine with per-stream bandwidth control
dispatch/slicing.rs	Micro-slicing framework for kernel fairness
dispatch/cache.rs	Kernel PTX cache with LRU eviction and TTL
transfer/pinned.rs	Pinned (page-locked) memory manager with pooling

Complete v0.2 Feature List (12 Features)

Core Infrastructure:

1. Rust Memory Pool - LRU eviction, size-class free lists
2. Rust Scheduler - Priority queue, memory reservation
3. Rust Transfer Engine - Separate H2D/D2H streams
4. Rust Kernel Dispatch - Per-stream limits, lifecycle tracking

NEW in this PR:
5. Admission Control - Deterministic admission, quota enforcement
6. QoS Policy Framework - 3-tier QoS (Guaranteed/Burstable/BestEffort)
7. Kernel Pacing Engine - Bandwidth-based throttling per stream
8. Micro-Slicing - Kernel splitting, round-robin fairness
9. Pinned Memory - Page-locked host memory with pooling
10. Kernel Cache - PTX caching, LRU eviction, TTL
11. GPU Partitioning - Resource isolation, multi-tenant support

Compute:
12. Tiled Matmul - Shared memory + double buffering

Benchmark Results (RTX 3090 Ti)

Matrix Size	Kernel	Time	Performance	vs NumPy
512x512	L2-opt	0.21ms	1262 GFLOPS	11.6x
1024x1024	L2-opt	1.59ms	1350 GFLOPS	2.2x
2048x2048	Tiled	3.89ms	4417 GFLOPS	6.1x
4096x4096	Tiled	20.97ms	6555 GFLOPS	7.9x

Peak: 6555 GFLOPS

Test Coverage

• 106 Rust tests passing
• Full PyO3 bindings for all new types
• Comprehensive demo: examples/demo_v02_full.py

Test plan

• All 106 Rust unit tests pass (cargo test)
• Demo script runs successfully (python examples/demo_v02_full.py)
• Benchmark shows expected performance (6555 GFLOPS peak)
• PyO3 bindings work correctly from Python
• No memory leaks in pinned memory manager
• Partition resource limits enforced correctly
