`pyghidra.analyze` fails to call `monitor` with `'NoneType' object is not callable`

[niooss-ledger]

Describe the bug
While using PyGhidra on Ghidra's master branch, I got:

Traceback (most recent call last):
  File "ghidra_analyze_and_export_programs.py", line 105, in analyze_and_export_all_programs
    pyghidra.analyze(program)
    ~~~~~~~~~~~~~~~~^^^^^^^^^
  File "/root/.config/ghidra/ghidra_12.1_DEV/venv/lib/python3.13/site-packages/pyghidra/api.py", line 177, in analyze
    monitor = monitor()
TypeError: 'NoneType' object is not callable

To Reproduce
Steps to reproduce the behavior:

1. On Debian 13, build and install Ghidra's current master branch (commit a0acfb8f914f77dd72a1a6661d501f758eef0a90, 12.1 DEV)
2. Launch support/pyghidraRun
3. In another terminal, launch a Python interactive console using PyGhidra's virtual environment with ~/.config/ghidra/ghidra_12.1_DEV/venv/bin/python3
4. Analyze some program, like /bin/true by entering the following Python code:

import pyghidra

pyghidra.start()
project = pyghidra.open_project("/tmp", "my_project", create=True)
loaded_program = pyghidra.program_loader().project(project).source("/bin/true").load()
program = loaded_program.getPrimaryDomainObject()
pyghidra.analyze(program)

5. Observe a Python exception

Traceback (most recent call last):
  File "<python-input-6>", line 1, in <module>
    pyghidra.analyze(program)
    ~~~~~~~~~~~~~~~~^^^^^^^^^
  File "/root/.config/ghidra/ghidra_12.1_DEV/venv/lib/python3.13/site-packages/pyghidra/api.py", line 177, in analyze
    monitor = monitor()
TypeError: 'NoneType' object is not callable

Expected behavior
No error

Screenshots
If applicable, add screenshots to help explain your problem.

Environment (please complete the following information):

• OS: Debian 13 with x86_64 CPU
• Java Version: OpenJDK Runtime Environment (build 21.0.9+10-Debian-1deb13u1)
• Ghidra Version: current master
• Ghidra Origin: Locally built from https://github.com/NationalSecurityAgency/ghidra

Additional context
Add any other context about the problem here.

This regression comes from commit c18c7a8 which modified pyghidra.api.analyze to:

def analyze(
        program: "Program", 
        monitor: Optional["TaskMonitor"] = None
    ):
    """
    Analyzes the given program.

    :param program: The Ghidra program to analyze.
    """
    from ghidra.app.script import GhidraScriptUtil

    from ghidra.program.util import GhidraProgramUtilities
    from ghidra.app.plugin.core.analysis import AutoAnalysisManager
    
    if monitor is None:
        monitor = monitor()

In the last line, monitor is a local variable which is None, so calling monitor() triggers the error.

Thanks, I'll get this fixed.
