th-kim0823 dfef65f196 feat(app): staleness module + post-process search hits (fb-32)
compute_stale: strict > boundary, threshold=0 disables, future
timestamps treated as fresh (clock skew safety). App::search
re-stamps on cache hit so config threshold changes take effect
without flushing the cache.

Also unblocks the workspace build by plugging placeholder
indexed_at/stale into the two AnswerCitation construction
sites in kebab-rag/pipeline.rs (the score-gate refusal path
forwards from SearchHit; the LLM-citation path uses
UNIX_EPOCH/false until Task 7 wires the real values through
pack_context).

//! p9-fb-32: `App::search` end-to-end staleness wiring.
//!
//! `compute_stale` itself is unit-tested in `kebab_app::staleness`; this
//! file proves the post-process actually fires through the full
//! retriever stack and that the cache-hit re-stamp respects the
//! configured threshold.
//!
//! All three tests run lexical-only (no AVX, no fastembed download).
