Install GhidraMCP 2.0 and connect it to Claude Desktop

Switch Ghidra to 12.1.4 (with openjdk-21-jdk), the version the
GhidraMCP 2.0 release is built for; Ghidra only loads extensions built
for its exact version.

From LaurieWired's GhidraMCP 2.0 release zip (SHA-256 checked):
- unpack the Ghidra extension into /opt/ghidra/Ghidra/Extensions; the
  build fails if it doesn't target GHIDRA_VERSION. GhidraMCPPlugin is a
  RELEASED Developer plugin, so the CodeBrowser config loads it, and it
  serves its HTTP backend on 127.0.0.1:8080.
- install the ghidra-mcp wheel into /opt/ghidra-mcp, with every
  dependency pinned to GhidraMCP's uv.lock at the release commit
  (ghidra/uvlock-to-constraints.py, honouring per-Python markers).

claude-desktop/claude_desktop_config.json adds a stdio "ghidra" server
running ghidra-mcp against http://127.0.0.1:8080/ and is copied into
~/.config/Claude.

Verified with a test project: ghidra-mcp started from that config
connected to Ghidra 12.1.4 in GUI mode and returned program info,
segments and imports for the open program.
