//! # 🧬 Long-read Somatic Variant Calling and Analysis Framework
//!
//! This Rust library provides a modular, parallelizable framework for somatic variant calling, annotation, and interpretation from long-read sequencing data. It is designed to support full pipelines for research and clinical workflows across multiple variant callers and analysis stages.
//!
//! The library also serves as an extensible platform that developers can leverage to add custom features, integrate new tools, and tailor workflows to specific use cases.
//!
//! ## 🧩 Key Features
//!
//! - **POD5 Demultiplexing and Alignment**: End-to-end support for processing ONT POD5 files:
//!     - Barcode-aware demultiplexing using metadata CSVs
//!     - POD5 subsetting and organization by case
//!     - Integration with basecallers (e.g., Dorado) for read alignment
//! - **Pipeline Management**: Full orchestration of Dockerized execution pipelines for tools such as ClairS, Nanomonsv, DeepVariant, Savana, Modkit, and Severus.
//! - **Flexible Configuration**: Centralized configuration system (`Config`, `CollectionsConfig`) for all modules and pipelines.
//! - **Input Abstraction**: Unified handling of BAM, POD5, and VCF file collections across cohorts and directories.
//! - **Variant Processing**: Modular loading, filtering, statistical analysis, and annotation of somatic and germline variants.
//! - **Haplotype Phasing and Methylation**: Support for LongPhase-based phasing and Modkit methylation pileups with support for multi-threaded pileup and aggregation.
//! - **Parallel Execution**: Uses `rayon` for efficient multicore parallelization over large cohorts and tasks.
//!
//! ## 📚 Module Highlights
//!
//! - `callers`: Interfaces to variant calling tools (ClairS, DeepVariant, Nanomonsv, Savana, etc...)
//! - `runners`: Pipeline runners (e.g. `Somatic`, `SeverusSolo`, `LongphasePhase`) that manage end-to-end execution.
//! - `collection`: Organizes input data across BAMs, VCFs, and POD5 files with auto-detection of completed runs.
//! - `annotation`: VEP line parsing and high-level annotation aggregation.
//! - `pipes`: Composition modules for executing pipelines across callers and post-processing steps.
//! - `functions`: Custom logic for genome assembly, entropy estimation, and internal tooling.
//! - `positions`, `variant`, `helpers`: Utilities for SV modeling, variant filtering, position overlap logic, and helper methods.
//!
//! ## ⚡ Workflow Overview
//!
//! ### 1. 📦 From POD5 to BAM Alignment
//!
//! - **Demultiplexing**: POD5 files are subset and demuxed using barcodes (via CSV metadata).
//! - **Flowcell Case Management**: Each sample is identified by a [`collection::pod5::FlowCellCase`] containing its ID, time point, and POD5 directory.
//! - **Alignment**: The [`commands::dorado::Dorado`] module handles alignment of POD5 reads to reference genome, producing BAMs.
//!
//! ```rust
//! let case = FlowCellCase { id: "PATIENT1", time_point: "diag", barcode: "01", pod_dir: "...".into() };
//! Dorado::init(case, Config::default())?.run_pipe()?;
//! ```
//!
//! ### 2. 🧬 Variant Calling (BAM ➝ VCF)
//!
//! Using the aligned BAMs, multiple variant callers can be run in parallel. The [`callers`] and [`runners`] modules support:
//!
//! - **ClairS** – somatic small variant calling with LongPhase haplotagging  
//! - **Nanomonsv** – structural variants (SV)  
//! - **DeepVariant** – germline small variants  
//! - **Savana** – SVs and copy number variations (CNV)  
//! - **Modkit** – methylation pileups  
//! - **LongPhase** – phasing and modcalling
//!
//! All workflows can be triggered per-case or per-cohort using `Collections` or `Somatic` runners.
//!
//! ```rust
//! ClairS::initialize("PATIENT1", Config::default())?.run()?;
//! NanomonSV::initialize("PATIENT1", Config::default())?.run()?;
//! ```
//!
//! ### 3. 📈 Aggregation & Statistics (VCF ➝ JSON / Stats)
//!
//! After variant calling:
//!
//! - Annotate with VEP ([`annotation`] module)
//! - Load and filter with [`variant::variant_collection`]
//! - Compute variant and region-level stats (e.g., mutation rates, alteration categories, coding overlaps)
//!
//! ```rust
//! let variants = Variants::load_from_json("/path/to/somatic_variants.json.gz")?;
//! let stats = VariantsStats::new(&variants, "PATIENT1", &config)?;
//! stats.save_to_json("/output/path/stats.json.gz")?;
//! ```
//!
//! ### 4. 🧠 Intelligent Task Management (`collection` module)
//!
//! - Auto-discovers available samples, POD5s, BAMs, and VCFs
//! - Detects missing outputs and creates task lists
//! - Tasks are parallelizable using Rayon and can be run on-demand
//!
//! ```rust
//! let mut collections = Collections::new(CollectionsConfig::default())?;
//! collections.todo()?;      // Identify missing steps
//! collections.run()?;       // Run them automatically
//! ```
//!
//! ## 🔬 Testing
//!
//! Integration tests demonstrate the entire pipeline. Run with logging enabled:
//!
//! ```bash
//! export RUST_LOG=debug
//! cargo test -- --nocapture
//! ```
//!
//! ## 🧪 Example Use Cases
//!
//! - Full somatic variant calling pipeline on matched tumor/normal samples
//! - POD5-based pipeline from raw signal to variants
//! - Aggregation and annotation of SVs across a clinical cohort
//! - Methylation analysis using nanopore-specific tools
//! - Variant calling and analysis in large-scale longitudinal studies
//!
//! ## 🚀 Getting Started
//!
//! All workflows are initialized from `Config` and driven by the `Collections` structure:
//!
//! ```rust
//! let collections = Collections::new(CollectionsConfig::default())?;
//! collections.todo()?;
//! collections.run()?;
//! ```
