Configs changes

[khezen]

Added

• Configurable DEFAULT_MAX_LLM_CALLS setting (default 30) controlling maximum LLM calls for RLM context-overflow fallback
• Configurable MIN_CONFIDENCE threshold (default 0.81) for filtering low-confidence issues
• Per-signature max_llm_calls override (SCOPE_MAX_LLM_CALLS, CODE_REVIEW_MAX_LLM_CALLS, SUPPLY_CHAIN_MAX_LLM_CALLS, SUMMARY_MAX_LLM_CALLS, DOC_MAX_LLM_CALLS, AUDIT_MAX_LLM_CALLS)
• ContextSafe now accepts max_iters and max_llm_calls parameters for per-module override

Changed

• default-max-iters action input default raised from 3 to 10
• Moved hardcoded MIN_CONFIDENCE constant from helpers.py to configurable Settings.min_confidence field (default 0.81)

Fixed

• RLM fallback previously hardcoded max_iters=10, max_llm_calls=20; now respects per-signature and global configuration
