serverdoctor 0.1.0

First release.

serverdoctor reads what a Minecraft server has already written — its log, its configuration files,
its start script, the jars in plugins/ — and reports what is wrong with it. It does not start a
server, connect to one, or load any plugin code, which is what makes it usable on the box that just
crashed and against jars you did not compile.

Five commands: scan for a whole server directory, then log, config, flags and plugins
individually. mcp serves the same audits to an AI coding agent over stdio, and rules prints the
catalogue.

Fifty-six rules. Each states one fact and names where that fact was read from: a file and line in
Paper or Folia, a JEP, or an API response. Some of what that turned up is worth knowing on its own:

• Paper deletes vanilla's Can't keep up! Is the server overloaded?, so on Paper the line never
  appears however far behind the server falls — and if your log has it, the log is not from Paper.
• timeout-time: -1 does not disable the watchdog. Paper substitutes 300 seconds. The only real kill
  switch is -Ddisable.watchdog, which is reported as critical.
• The EULA refusal is logged at INFO, which is why a panel showing only errors reports a clean
  shutdown and no reason.
• folia-supported: true is the single thing Folia checks at load, and it is written by the plugin's
  author.

Requires Java 21 or newer. The jar is self-contained; the network is used only by
plugins --online.
