PocMap v2.1.0

First PyPI release — pip install pocmap / pipx install pocmap.

This release turns PocMap from a hardened library into an adoptable tool:

• Caching & offline — persistent TTL'd HTTP cache; --offline / POCMAP_OFFLINE.
• Machine output everywhere — --format {table,json,csv,md,sarif}; SARIF 2.1.0 on latest/discover for code scanning.
• CI gate — bulk - (stdin), --fail-on {critical,high,kev,epss>=N} → exit 6.
• Monitoring — latest/discover --diff (snapshot delta) + --notify <webhook>.
• Diagnostics — pocmap doctor, pocmap cache info|clear; shell completion.
• Pluggable exploit sources — pocmap.exploit_sources entry points (see examples/example-exploit-source/).
• Fixes — restored MCP GitHub-PoC discovery; stop swallowing our own bugs; no webhook-URL credential leaks.
