/**
 * Pure inference of the monorepo container directory from a list of
 * scan paths.
 *
 * Each `ScanPath` carries a `boundaryPath` ending in the `fjall` marker
 * segment. Stripping that segment yields the container — the directory
 * between repo root and the `fjall/` boundary. For multiple paths, returns
 * the longest common ancestor.
 *
 * Edge cases:
 *   - empty array                       → `null`
 *   - boundary at repo root (`fjall`)   → `null`
 *   - single nested boundary            → its parent directory
 *   - two with a common ancestor        → the ancestor
 *   - two with no common ancestor       → `null`
 *
 * Pure function — no I/O. Used by both the CLI scaffold pre-flight
 * (`scanLocalRepository`) and the webapp scan endpoint
 * (`scanInfrastructureFiles`) to suggest a default `--container` for new
 * apps.
