ifcquery, ifcedit, ifcmcp: add documentation

Add ifcquery, ifcedit and ifcmcp to the README contents table, the
Sphinx docs toctree and introduction utilities table. Add new .rst
pages for each package documenting subcommands, installation, usage,
and parameter types. Fix plot and render CLI examples in ifcquery
README to use -o/--out-format flags. Update ifcmcp README to use the
installed ifcmcp command rather than python3 -m ifcmcp.

+IfcEdit
+=======
+
+IfcEdit is a CLI wrapper for the full ``ifcopenshell.api`` mutation API. It
+exposes all editor functions — over 350 across 30+ modules — without requiring
+you to write a Python script. It supports four subcommands:
+
+- **list** — list all API modules, or all functions within a module
+- **docs** — show full documentation for a function (parameters, types, descriptions)
+- **run** — execute a mutation against an IFC file
+- **quantify** — run quantity take-off using ifc5d rules; requires the IfcOpenShell C++ geometry bindings
+
+Installation
+------------
+
+::
+
+    pip install ifcedit
+
+Or install from source:
+
+1. :doc:`Install IfcOpenShell <ifcopenshell-python/installation>`
+2. `Clone the IfcOpenShell repository <https://github.com/IfcOpenShell/IfcOpenShell>`_.
+3. ``cd /path/to/IfcOpenShell/src/ifcedit``
+4. ``pip install .``
+
+Usage
+-----
+
+Discover available API functions::
+
+    $ ifcedit list
+    $ ifcedit list root
+    $ ifcedit list geometry
+
+Read documentation for a function::
+
+    $ ifcedit docs root.remove_product
+    $ ifcedit docs type.assign_type
+
+Execute a mutation (overwrites the input file by default)::
+
+    $ ifcedit run model.ifc root.remove_product --product 42
+    $ ifcedit run model.ifc type.assign_type --related_objects 10 --relating_type 20
+
+Write to a separate output file::
+
+    $ ifcedit run model.ifc root.create_entity -o output.ifc --ifc_class IfcWall
+
+Dry-run to validate without modifying the file::
+
+    $ ifcedit run model.ifc root.remove_product --dry-run --product 42
+
+Quantity take-off (writes ``IfcElementQuantity`` psets back to the file; requires C++ geometry bindings)::
+
+    $ ifcedit quantify list
+    $ ifcedit quantify run model.ifc IFC4QtoBaseQuantities
+    $ ifcedit quantify run model.ifc IFC4QtoBaseQuantities --selector IfcWall
+    $ ifcedit quantify run model.ifc IFC4QtoBaseQuantities -o model_qto.ifc
+
+Parameter types
+---------------
+
+IfcEdit automatically coerces CLI string arguments to the correct Python types
+using the type hints on each API function:
+
+.. list-table::
+   :header-rows: 1
+
+   * - Type
+     - CLI input
+     - Python value
+   * - ``str``
+     - ``"hello"``
+     - ``"hello"``
+   * - ``int``
+     - ``"42"`` or ``"#42"``
+     - ``42``
+   * - ``float``
+     - ``"3.14"``
+     - ``3.14``
+   * - ``bool``
+     - ``"true"``, ``"1"``, ``"yes"``
+     - ``True``
+   * - ``Optional[X]``
+     - ``"none"``
+     - ``None``
+   * - ``entity_instance``
+     - ``"42"`` or ``"#42"``
+     - resolved from model by step ID
+   * - ``list[entity_instance]``
+     - ``"5,6,7"``
+     - list of resolved entities
+   * - ``dict``
+     - ``'{"key": "val"}'``
+     - parsed JSON object
+   * - ``Literal["A", "B"]``
+     - ``"A"``
+     - validated against allowed values
