Add file and database loading examples to Python cookbook

[Copilot]

Adds comprehensive examples to the Python script cookbook demonstrating how to work with Binary Ninja files and databases, covering both UI scripting and headless usage scenarios.

Changes Made

UI Scripting Context

• Explains that the bv magic variable is available when scripting from the Binary Ninja UI (Python console or File -> Run Script...)

Headless Usage (Commercial+)

• Documents headless file loading using the load() function for standalone scripts
• Clarifies that headless usage requires Binary Ninja Commercial and above (Commercial, Ultimate, and Enterprise)
• Includes note that this feature is not available in Personal edition

Code Examples

• Basic file loading: Shows both context manager pattern (recommended) and manual close pattern
• Loading with options: Demonstrates customizing load behavior with various options
• Loading databases: Shows that .bndb files use the same API as regular binaries
• Controlling analysis: Demonstrates disabling automatic analysis for performance

Implementation Details

• Added new "Loading Files & Databases" section as the first recipe in the cookbook
• Follows existing cookbook style and conventions
• Concise documentation (54 lines) with clear, practical examples

Comments on the Issue (you are @copilot in this section)

@xusheng6 The `load` function can do it and is the preferred way. It would be nice to also include an example of loading the file with options

@copilot

1. also mention the headless using of binary ninja and loading of a file only works in binary ninja commercial and above. It does not work in the personal version
2. Consolidate the text a bit -- it is too wordy now

Done. Added a note about Commercial/Enterprise requirement and consolidated the text significantly (reduced from 87 to 54 lines). Changes in commit 3594847.

@copilot better clarify this is only available in Binary Ninja Commercial and above (including Commercial, Ultimate, Enterprise)

@copilot Add to the start that if you are doing the scripting from the UI, the bv magic variable is already defined and you can directly use it in the Python console or a script loaded via File -> Run Script...

Then mention if you have commercial and above, you can use Binary Ninja headlessly (i.e., using it as a library), and went on to mention the examples

@copilot Add to the start that if you are doing the scripting from the UI, the bv magic variable is already defined and you can directly use it in the Python console or a script loaded via File -> R...

Added introductory text explaining that bv magic variable is available when scripting from UI (Python console or File -> Run Script...), followed by explanation that Commercial and above editions enable headless usage as a library. Changes in commit 6a36895.
