feat: Add --array CLI flag for batch processing (ADR-0007 Phase 6)

Implements Phase 6 of ADR-0007: CLI integration for array mode.

Changes:
- Added --array flag to optsAgent struct and apply() method
- Implemented validate() method to check for incompatible flags (--array with --merge)
- Updated optsAgent.build() to call ArrayMode() when --array flag is set
- Added ArrayMode() method to worker builder that adds ArrayCollector processor
- Enhanced CLI help text with array mode examples and documentation

The --array flag enables batch processing by collecting all input documents
into an array. The workflow can then access this array via 'selector: document'
in foreach steps. This is useful for:
- Processing JSON array files
- Batch processing split documents
- Multiple files as array

Memory warning: All documents are buffered in memory until EOF.

Validation ensures --array and --merge are mutually exclusive since they
represent different semantics (array collection vs document merging).
