Consolidates four extract paths and two extract-chunk-embed-write pipelines into a single shared encoding module. Fixes the embedder lifecycle divergence between watcher and /api/reindex (no more 200MB reload per reindex click) and unifies failure tracking so /api/reindex failures now surface in SettingsPanel "Ingest Health". New files: - scripts/encoding.py — extract_text, chunk_text, chunk_and_embed, write_embeddings_batch - scripts/failures.py — record_ingest_failure, resolve_ingest_failure (shared by watcher.py and ingest.py) Refactored: - scripts/watcher.py — drops local extract/chunk/embed implementations and CHUNK_SIZE/CHUNK_OVERLAP/SUPPORTED constants; imports from encoding and failures. Now writes ingest_failures row on empty-text-extract (was silent return 0). - scripts/ingest.py — substantial rewrite. Exposes ingest_directory(folder, embedder=None) for in-process invocation; CLI back-compat preserved via ingest_folder wrapper. Module-level SentenceTransformer load removed. - scripts/corpus_integrity.py — imports extract_text from encoding; extract_text_for_retry function removed. - scripts/api.py — /api/reindex rewritten with BackgroundTasks (uses module-level embedder; no subprocess); new /api/reindex/status endpoint reading ~/aaronai/reindex_status.json; /api/corpus/retry imports extract_text from encoding; INGEST_SCRIPT constant removed (dead after this refactor); 409 reentrance guard prevents double-click stomping. Behavior changes: - /api/reindex no longer subprocess.Popens; runs in FastAPI BackgroundTasks threadpool, doesn't block API thread. - /api/reindex no longer reloads SentenceTransformer on each click. - /api/reindex failures newly write to ingest_failures (visible in SettingsPanel "Ingest Health" — badge will jump on first reindex). - New embeddings rows always have created_at = NOW() (canonical, server-side). - New embeddings rows always include metadata.folder field (None when not derivable). - /api/reindex returns 409 on second click while a job is running. - New /api/reindex/status endpoint for polling. Existing 9,815 NULL created_at rows remain unchanged; backfill is a separate decision if desired. 199 insertions, 256 deletions across 6 files (codebase shrinks net).

Pre-commit verification: BackgroundTasks already imported, sys.path resolves correctly via script-path semantics, static import clean.
