rollback zip changes

Move operators and preferences out of __init__.py into dedicated modules.
Fix cyclic import by using proper AddonPreferences pattern. Replace
implicit .zip extension detection in CLI with explicit -z/--zip flag.

+# Version 1.21 (2025-11-24)
+
+- Require Python version 3.11 or newer. Versions up to Python 3.14 are supported.
+- Skip packed blend files. BAT will assume that the packed file is self-contained, i.e. any asset used by a packed blend file should also be packed.
+- Support Geometry Node simulation caches ([#92890](https://projects.blender.org/blender/blender-asset-tracer/pulls/92890)).
+- Add a `py.typed` marker file, such that tooling like mypy know BAT has type annotations ([#92895](https://projects.blender.org/blender/blender-asset-tracer/pulls/92895)).
+- Add support for getting individual array items ([#92898](https://projects.blender.org/blender/blender-asset-tracer/pulls/92898)) and iterating dynamic arrays (part of [#92890](https://projects.blender.org/blender/blender-asset-tracer/pulls/92890)).
+- Support setting sub-properties via `block.field_set()` ([#92899](https://projects.blender.org/blender/blender-asset-tracer/pulls/92899)).
+- Make `bat blocks` print the biggest block memory address as hexadecimal ([#92900](https://projects.blender.org/blender/blender-asset-tracer/pulls/92900)).
+
+
+# Version 1.20 (2025-07-11)
+
+- Add support for Blender 5.0 compositor node trees ([16c208bc8e13](https://projects.blender.org/blender/blender-asset-tracer/commit/16c208bc8e130c8b1233bdb411ecabdab19af3c5)).
+- Make it possible to run BAT with `python -m blender_asset_tracer` ([6c42d06f0590](https://projects.blender.org/blender/blender-asset-tracer/commit/6c42d06f05909d4ac2096e84557d19dd93382f3a)).
+- Add support for loading the file sub-version ([4c429e921228](https://projects.blender.org/blender/blender-asset-tracer/commit/4c429e921228259f47795f8ad913ad3eff8fac71)).
+
+
+# Version 1.19 (2025-06-16)
+
+- Add support for tracing dynamic paint caches ([#92889](https://projects.blender.org/blender/blender-asset-tracer/pulls/92889)).
+- Add support for the large blendfile header blocks ([#92893](https://projects.blender.org/blender/blender-asset-tracer/pulls/92893)). This is necessary for compatibility with Blender 5.0.
+- Drop support for Python 3.8.

 # Version 1.18 (2024-01-11)
 
 - When logging that there is no reader implemented for a certain data-block type, the filepath of the blend file that contains that data-block is now included in the message ([#92885](https://projects.blender.org/blender/blender-asset-tracer/pulls/92885)).
