Add Canny listing

[AsafMazuz1]

What changes and why?

Adds Canny (https://github.com/qkal/Canny) under Developer tools: append-only session ledger and deterministic done-gate for Claude Code/Codex; optional TypeSafe Jev advises but never alone blocks. Distinct from jev-guard/toolgate (per-tool risk) and from open PR #7 belay.
