Project dependency capture + workdir staging (Phase 09 — Track D.1 + D.2). +//! +//! [`capture_project_dependencies`] reads the user's project root and +//! produces a [`CapturedDeps`] record describing every artifact the +//! harness will need at runtime — toolchain pin, direct imports of the +//! entry file, web framework signal, and local config files reachable +//! from the entry point. [`stage_workdir`] then materialises a minimal +//! copy of those artifacts into the per-spec workdir so the sandboxed +//! harness can `import flask` (or its per-language equivalent) inside an +//! offline sandbox without leaking the whole project tree across the +//! filesystem boundary. +//! +//! The lang-specific manifest (`requirements.txt`, `package.json`, +//! `Cargo.toml`, …) is then synthesised by the per-language emitter via +//! [`crate::dynamic::lang::LangEmitter::materialize_runtime`] from the +//! [`Environment`] handed back by `stage_workdir`. +//! +//! ## Scope +//! +//! - Direct imports of the spec's entry file (tree-sitter walk, top-level +//! `import` / `require` / `use` only — transitive imports are deferred +//! to a future phase). +//! - Framework deps inferred from [`crate::utils::project::detect_frameworks`]. +//! - Local config files reachable from the entry point's directory +//! (`config.yaml`, `config.yml`, `.env`, `appsettings.json`, plus the +//! toolchain-resolver-recognised manifest itself). +//! - Source files reached via reverse callgraph closure from the sink's +//! enclosing function. Bounded by [`MAX_WORKDIR_BYTES`] so a +//! pathological closure does not copy the entire repository. +//! +//! The staged workdir is intentionally minimalist: every file copied has +//! to either be the entry, a dep manifest, a config file, or an in-closure +//! source file.
