0.6.0

Added

• Per-group usage examples: every tool group now has a prompt-plus-call
  example in docs/examples.md.
• Boolean flags accept an explicit value: --read-only=false switches off
  MS365_MCP_READ_ONLY=true, using the same vocabulary as the environment
  variables.
• permissions annotates cross-group scopes with a one-clause reason, so
  files -> Mail.Read and the search index scopes explain themselves.

Changed

• README slimmed to an overview; detail sections moved to docs/
  (auth, configuration, tools, examples, troubleshooting, security,
  agents, why).
• status reports the exposed tool count (36 under --read-only,
  6 under --discovery) instead of the raw catalogue total.
• status names dropped groups inline with the --org-mode remedy
  instead of printing an empty group list.
• logout with no session says nothing was removed rather than
  claiming it deleted files.
• --groups is case-insensitive, like --preset.
• --help documents that --preset and --groups combine by union.
• permissions closing line now distinguishes Microsoft's classification
  from the tenant consent policy gate.

Fixed

• Help examples used the nonexistent microsoft-graph-mcp command;
  every user-facing command string now uses the real ms-graph-mcp bin.
• A bad environment value no longer defeats --help/--version;
  real commands still fail fast on it.
• Non-login commands warn on stderr when --scopes/--full would
  be silently ignored.
