Ship the minimum primitive for self-modifying pipelines (#132): a step type that re-reads the active .ail.yaml, swaps session.pipeline in place, and re-anchors the top-level sequential executor by step-id so newly-added tail steps execute in the same run. Previously the only way for an LLM-edited pipeline to take effect was on the next ail --once invocation — the executor captured a static Vec<Step> at startup. spec/core/s21 framed this as "deferred / between runs only"; that framing was incorrect. A minimum-viable mid-run reload is achievable without the full diff-application / FROM-layering / log-injection machinery. Surface: action: reload_self. Anchor-by-id resumption. Hard cap of MAX_RELOADS_PER_RUN = 16. Typed ail:pipeline/reload-failed error for passthrough (no source), cap exhaustion, validation failure, and missing-anchor. Turn-log entry records the before/after step count. Clean up pre-existing clippy/unused-import warnings across the workspace so the build is warning-free.
