Add pip versioned installation docs for pmll-memory-mcp

[Copilot]

pmll-memory-mcp is installable via pip but neither README documented it — leaving users without guidance on version pinning or switching between releases.

Changes

• mcp/README.md — New ### Via pip (Python ≥ 3.11) section covering:

  • Latest and version-pinned install commands
  • Version-switching pattern (uninstall + reinstall)
  • pmll-memory-mcp / python -m pmll_memory_mcp.server startup commands
  • pip variants of Claude Desktop and VS Code MCP config blocks

• README.md — Updated PMLL MCP Server installation section with the same pip guidance alongside the existing npm/npx instructions

# Install a specific version
pip install pmll-memory-mcp==0.1.0
pip install pmll-memory-mcp==0.2.0  # replaces 0.1.0

# Switch versions
pip uninstall -y pmll-memory-mcp
pip install pmll-memory-mcp==0.1.0

Claude Desktop config for pip-installed server:

{
  "mcpServers": {
    "pmll-memory-mcp": {
      "command": "pmll-memory-mcp"
    }
  }
}

Original prompt

To install a specific version, run one command at a time:

pip install pmll-memory-mcp==0.1.0
pip install pmll-memory-mcp==0.2.0

Notes:

• If you run both, the second command will upgrade/replace 0.1.0 with 0.2.0 (so you’ll end up on 0.2.0).
• To switch versions, explicitly install the version you want (or uninstall first):
  pip uninstall -y pmll-memory-mcp
  pip install pmll-memory-mcp==0.1.0
