feat: add bridge script for Claude Code → LM Studio execution (v3.12.1)

Bridge script enables local execution of Claude Code plans via LM Studio:
- Python CLI with 5 components (DoobidooReader, LMStudioClient, Validator, StepExecutor, PlanExecutor)
- JSON Schema for plan validation (bridge-plan-schema.json)
- Cost optimization: Plan with Opus (~$0.50-2), execute free locally (80-90% savings)
- 4 validation types: json, syntax_check, contains_keys, non_empty
- CLI: --health, --list, --plan ID, -v verbose mode

Documentation:
- New section "Local Execution Bridge" in ultimate-guide.md §11.2
- scripts/README.md with full usage documentation
- machine-readable/reference.yaml entries for discoverability
