CONF-022: Server negotiates an outdated initialize-era revision

Severity	Applies to	Spec section
info	legacy era, stdio, http	2025-11-25/basic/lifecycle#version-negotiation

When asked for 2025-11-25, a server SHOULD answer with the latest version it supports. This notes servers whose latest is 2025-03-26 or 2024-11-05: MCPProbe only detects those revisions and recommends upgrading. Info: an old revision is not a violation.

From the command line: mcpprobe checks explain CONF-022. To leave it out of a run, add "CONF-022" to [checks] disable in mcpprobe.toml; to change how much it counts, use severity_overrides.
