Add skip_translate_if_provided option to bypass translation when target exists (multi-task mode only)

[Copilot]

Implements optional translation skipping when input data already contains translations in the target column. This feature is only available for multi-task mode.

Changes

Multi-task mode (agents/modules/multitasker.py)

• Skip translate step when skip_translate_if_provided: true and valid target exists
• Pipeline proceeds directly to postedit → proofread

Configuration

• Added skip_translate_if_provided: false to multi.yaml
• Default false preserves existing behavior

Documentation

• Updated README.md to clarify feature is multi-task mode only
• Added complete example configuration for multi-task mode

Skip conditions (all required):

• Config option enabled
• target field exists, is string type, and non-empty

Usage

skip_translate_if_provided: true

model:
  translate:
    name: gpt-4.1-mini-2025-04-14
    temperature: 0.7
    max_tokens: 2048
  postedit:
    name: gpt-4o
    temperature: 0.7
    max_tokens: 1024
  proofread:
    name: gpt-5
    temperature: 0.7
    max_tokens: 1024

With this enabled in multi-task mode, rows containing translations in the target column bypass the translate agent entirely and proceed directly to postedit → proofread.

@copilot You're right that this feature should only be applied to multitasker, not on singletasker.

Removed the feature from single-task mode. The skip_translate_if_provided option now only applies to multitasker. Changes reverted in commit f812d0f.

Prefer the default value to be True.
