Feat/configurable sanitizers and js precision (#32)

* chore: Exclude CLAUDE.md from Cargo.toml

* feat: Add configurable analysis rules and CLI commands for custom sanitizers and terminators

* feat: Enhance resource management and analysis efficiency

- Implemented parallel summary merging in `scan_filesystem` using rayon for improved performance.
- Introduced `GlobalSummaries::merge()` for efficient merging of summaries.
- Optimized file reading and hashing to eliminate redundant I/O operations.
- Added `should_scan_with_hash()` and `upsert_file_with_hash()` methods to streamline file processing.
- Enhanced taint analysis with in-place mutations to reduce memory allocations.
- Updated resource acquisition patterns to exclude false positives for `freopen` and wrapper functions.

* feat: Implement severity downgrade for findings in non-production paths and add source kind inference

* feat: Update versioning information in SECURITY.md for new stable line
