Add ifcedit: CLI wrapper for ifcopenshell.api mutation functions (#7846)

ifcedit is a new command-line tool for executing ifcopenshell.api mutations from the shell. It wraps the entire API surface — any function callable via ifcopenshell.api can be invoked without writing Python.

Subcommands:

    list [module] — list all API modules, or functions within a module
    docs <module.function> — full documentation (params, types, descriptions)
    run <file> <module.function> [--param value ...] — execute a mutation; overwrites input file by default, or use -o <output> to write elsewhere; --dry-run validates without executing
    quantify list — list available QTO rules
    quantify run <file> <rule> — run quantity take-off, writing IfcElementQuantity psets back to the file

Parameter coercion: entity references can be passed as step IDs (strings); lists, dicts, booleans, and None are handled automatically.

Usage:

python3 -m ifcedit run model.ifc root.remove_product --product 42
python3 -m ifcedit docs geometry.edit_object_placement
