Adds a pure-Python interactsh client as a second-priority callback provider, sitting between webhook.site (primary) and interactsh-client CLI (fallback). This enables OOB testing via app.interactsh.com's protocol without requiring the Go binary to be installed. Protocol implementation: - RSA-2048 keypair generation for secure interaction retrieval - POST /register with base64-encoded PEM public key - GET /poll with AES-256-CTR + RSA-OAEP decryption of interactions - POST /deregister for cleanup on reset - Tries all 6 public interactsh servers (oast.pro/live/site/online/fun/me) - Supports INTERACTSH_SERVER env var for custom/self-hosted servers Provider priority: webhook_site → interactsh_api → interactsh_cli Changes: - tools/callback.py: Add _InteractshSession, crypto helpers, register/poll/deregister - tests/test_callback.py: 55 tests covering all 3 providers, crypto round-trip, fallback orchestration, deduplication, and tool method behavior - capability.yaml: Add cryptography>=41.0 dependency Closes CAP-1143
