fix(w47): Full-week hostile review fixes — W48 test baseline + WASM bundle constraint

Full-week hostile review (0C/1M/3m):
- M1: W48 plan test baseline updated from 1013 to 1027 (4 files, 8 occurrences)
- m2: GO/NO-GO W47 commit range extended to Day 6 (239d3d2)
- m3: WASM bundle size constraint updated to <700KB (actual: 622KB with PQ)

Returns `weight` if metadata field matches value (including `StringArray.contains(value)` for array fields), else `0.0`. Type mismatch returns `0.0` (no error). `BoostError` enum for construction-time validation. Max 200 lines. `cargo build` succeeds |
 | W48.1b | Add `search_boosted()` to `FilteredSearcher` in `src/filter/filtered_search.rs` | RUST_ENGINEER | 3h | Unit | `pub fn search_boosted(&mut self, query: &[f32], k: usize, boosts: &[MetadataBoost], filter: Option<&FilterExpr>, strategy: FilterStrategy) -> Result<FilteredSearchResult, FilteredSearchError>`. Semantics: run `search_filtered()` with `oversample = (k * 3).max(50).min(500)`, then rerank results by MULTIPLICATIVE boosting: `final_distance = raw_distance * (1.0 - boost_factor)` where `boost_factor = sum(boost_i.compute_boost(meta_i)).clamp(-1.0, 0.99)`. This is scale-independent: a weight of 0.3 with one match reduces distance by 30%, regardless of whether L2 distances are 0.001 or 50000. Returns top-k by final_distance. If boosts is empty, delegates to `search_filtered()`. `cargo build` succeeds |
