added default value and optimized xpath

[sauravpanda]

Summary by cubic

Adds default values for workflow inputs and prioritizes XPath-based selectorStrategies for clicks to improve reliability and meet 139-add-ai-strategy-selection. Prompts now show and use defaults, and clicking uses evaluated XPath when provided, with semantic strategies supported via the selector map.

• New Features

  • Support default values in WorkflowInputSchemaDefinition; CLI shows and uses defaults.
  • Prioritize step.selectorStrategies; XPath clicks executed via JS evaluation (more reliable).
  • Added XPath optimizer to generate robust alternatives from absolute XPaths.
  • Optional target_text validation with clear errors when strategies fail.

• Refactors

  • ElementFinder executes XPath via page.evaluate and supports semantic strategies via selector_map.
  • Text-first click no longer blocks when a selector exists; falls back with warnings.
  • Minor typing cleanups; bumped workflow-use to 0.2.9.

<violation number="1" location="workflows/workflow_use/workflow/element_finder.py:99">
Returning a hard-coded index of 0 breaks both callers—service.py will click the wrong element and semantic_executor.py will raise because it expects a selector string.</violation>

<violation number="2" location="workflows/workflow_use/workflow/element_finder.py:107">
By short-circuiting with “Strategy type … not yet supported”, every non-XPath strategy (text_exact, role_text, aria_label, etc.) now always fails, even though the selector generator and existing tests still rely on them. This regresses the core semantic matching behavior.</violation>

<file name="workflows/workflow_use/healing/xpath_optimizer.py">

<violation number="1" location="workflows/workflow_use/healing/xpath_optimizer.py:138">
Dynamic attribute and text values need escaping before embedding in XPath literals; otherwise any single quote in the value produces an invalid selector.</violation>
