Nano Agent, Mega Senses: Adding LSP to the 260-Line Coding Agent

A fork of the nanocode minimal coding agent (originally ~260 lines of Java) that adds optional Language Server Protocol support via Eclipse JDT Language Server. When a Java workspace is detected, the agent can download and start JDT LS, exposing three new tools to the LLM: java_definition (go-to-definition), java_hover (type info and Javadoc), and java_diagnostics (compiler errors). This gives the model classpath-aware, compiler-backed answers instead of relying solely on grep and file reads. The post walks through the architecture, practical prompt examples, trade-offs (JDT weight, token costs, trust model), and includes LspProbe.java for testing LSP without an LLM API key.
