Pyarmor

**Fixed isssues**
* Fix issue 2095: In Python 3.13, the script geretated by `--mix-str` will be crashed in runtime

**Fixed isssues**
* Fix issue 2071: In Python 3.13, if enable `clear_frame_locals`, executing the obfuscated scripts may crash randomly
* Fix issue 2082: In Python 3.13, when using BCC mode for nest function with closures, the obfuscated script will raise exception `'builtin_function_or_method' object does not support the context manager protocol`
* Fix issue 2087: When building extensions for linux.aarch64, linux.x86 and freebsd.x86_64, remove unnecessary flag `-lcrypt`
* Fix issue: `pyarmor build` generates `__init__.py` in the wrong location with wrong name
* Fix issue: `pyarmor build --mini` should not refactor scripts
* Fix issue: `pyarmor build --rft` failed for some special scripts
* Fix issue: `pyarmor build --mini` failed for some special scripts

**Changed features**
* Rename configuration `rft:auto_export_mode` to `rft:export_mode`
* `pyarmor init` redefines option `-r`, now it need one value 0-3 to specify search mode
* No auto-search project items if only `--src` is specified, instead using option `-r 3`. For example `pyarmor init -s src -r 3`

**Fixed isssues**
* Fix issue: When using `pyarmor build --mini-rft` to generate the scripts, if `rft:builtin_mode` is enabled, the obfuscated scripts may not work

**New features**
* New commands: `pyarmor init`, `pyarmor env`, `pyarmor build`
* New obfuscated scripts: mini, rft
