/**
 * Collapse doubled ".a5c/runs" segments in a path.
 *
 * When a relative path containing `.a5c/runs/...` is resolved from a working
 * directory that is itself inside `.a5c/runs/`, the result can contain the
 * segment twice (or more). This function collapses all consecutive duplications
 * into a single occurrence.
 *
 * Handles both forward-slash (Unix) and back-slash (Windows) separators as
 * well as mixed-separator paths.
 *
 * @example
 * collapseDoubledA5cRuns("/project/.a5c/runs/.a5c/runs/01RUN")
 * // => "/project/.a5c/runs/01RUN"
 *
 * @example
 * collapseDoubledA5cRuns("C:\\project\\.a5c\\runs\\.a5c\\runs\\01RUN")
 * // => "C:\\project\\.a5c\\runs\\01RUN"

/**
 * Resolve an input file path robustly, accounting for the CLI being invoked
 * from inside a task directory (or any subdirectory of `.a5c/runs/`).
 *
 * The standard `path.resolve(inputPath)` resolves relative to
 * `process.cwd()`. When the working directory is a task directory such as
 * `/project/.a5c/runs/RUN/tasks/TASK/`, resolving a relative path like
 * `.a5c/runs/RUN/tasks/EFFECT/file.json` produces a doubled path:
 * `/project/.a5c/runs/RUN/tasks/TASK/.a5c/runs/RUN/tasks/EFFECT/file.json`
 *
 * This function detects that situation and resolves relative to the project
 * root instead.
 *
 * **Resolution rules (in order):**
 * 1. `"-"` (stdin sentinel) — returned as-is.
 * 2. Absolute paths (including Windows drive letters like `C:\`) — normalized
 *    and returned.
 * 3. If `inputPath` contains a `.a5c/runs` segment **and** the current
 *    working directory is itself inside a `.a5c/runs` subtree — resolve
 *    relative to the detected project root.
 * 4. Otherwise — standard `path.resolve(inputPath)`.
 * 5. `collapseDoubledA5cRuns` is always applied as a final safety net.
 *
 * @param inputPath  The raw path argument supplied by the user or script.
 * @returns          A fully resolved, absolute path (or `"-"` for stdin).
 *
 * @example
 * // CWD = /project/.a5c/runs/RUN/tasks/TASK
 * resolveInputPath(".a5c/runs/RUN/tasks/EFFECT/input.json")
 * // => "/project/.a5c/runs/RUN/tasks/EFFECT/input.json"
 *
 * @example
 * resolveInputPath("/absolute/path/to/file.json")
 * // => "/absolute/path/to/file.json"
 *
 * @example
 * resolveInputPath("-")
 * // => "-"
