Add create-issues.sh: 25 GitNexus feature-parity issues for rust-sniffer

[Copilot]

rust-sniffer currently implements only the ingestion/parsing layer of GitNexus (~5–10% of its feature surface). This PR adds a ready-to-run script that creates all 25 GitHub issues mapping the full GitNexus feature set onto rust-sniffer, with dependency cross-references and priority labels.

Script (rust-sniffer/create-issues.sh)

• Creates 13 colour-coded labels (p0-foundation → p6-ai, graph, mcp, search, routes, etc.) — idempotent
• Creates all 25 issues in dependency order with full bodies
