Add missing context window entries for SageMaker models.
The new SageMaker JumpStart models nvidia-nemotron-3-nano-30b and qwen3-vl-8b-instruct are missing context window entries in contextWindows.ts. Without these entries, the system will incorrectly apply the sagemaker provider's default of 128,000 tokens.
Based on the inline comment in enums.ts (1M context for Nemotron 3 Nano) and the existing AWS variant entry (256,000), add:
"nvidia-nemotron-3-nano-30b": 1_000_000(or verify actual spec)"qwen3-vl-8b-instruct": [spec](need to verify official context window)

Line 72: Fix Bedrock model ID for Claude Opus 4.6 — missing inference version qualifier
Line 72 has an incorrect model ID. The official AWS Bedrock ID for Claude Opus 4.6 is anthropic.claude-opus-4-6-v1:0, but the code has anthropic.claude-opus-4-6-v1 (missing the :0 suffix). This will cause runtime model resolution failures. Line 73 is correct and matches the official Bedrock ID for Claude Sonnet 4.6.
Current state vs correct model IDs
Line 72 (incorrect):
CLAUDE_4_6_OPUS = "anthropic.claude-opus-4-6-v1",
Should be:
CLAUDE_4_6_OPUS = "anthropic.claude-opus-4-6-v1:0",

- Test integrity (8): false-pass prevention, keyword validation, boundary condition tests
- Code quality (16): ErrorFactory consistency, dead code removal, PWA compliance, formatting

What This PR Does
This is a comprehensive enhancement release for the NeuroLink SDK that spans models, observability, RAG, providers, CLI, landing page, and code quality. The changes originated from a feature branch that accumulated work across multiple areas, consolidated with 45 code review fixes from a prior review cycle. The goal is to bring the SDK up to date with the latest model generations (Claude 4.6, GPT-5.x, Gemini 3), add production-grade observability via OpenTelemetry, improve RAG document processing for real-world use cases, harden provider integrations, and clean up patterns across 24 files for consistency and maintainability.
