Typo-generation configuration

TypoGenerationConfig contains settings shared by every task in one generation run:

• language;
• use_excluding_set;
• horizontal_vs_vertical.

Individual sampling policies are represented by TypoGenerationTask. Each task defines:

• its typo-operation distribution;
• its typo rate;
• its generation attempts per eligible word;
• its minimum eligible word length.

Default CLI task set

The CLI uses create_default_typo_generation_tasks() to construct the ordered default task sequence:

• one forced single-error task for each supported operation distribution;
• one mixed two-error task.

The required CLI arguments are:

Argument	Runtime setting
--single-attempts COUNT	Attempts per word for each forced single-error task
--multi-attempts COUNT	Attempts per word for the mixed two-error task
--multi-min-length LENGTH	Minimum word length for the mixed two-error task

Shared generator settings use:

Argument	Runtime setting
--language LANGUAGE	TypoGenerationConfig.language
--excluding-set / --no-excluding-set	TypoGenerationConfig.use_excluding_set
--keyboard-weights HORIZONTAL VERTICAL	TypoGenerationConfig.horizontal_vs_vertical

Execution setting

--workers COUNT becomes the pipeline's n_workers argument. Worker count is not part of TypoGenerationConfig because it changes how the requested work is executed, not the requested generation semantics.
