* fix(ssa): ungate debug_assert_bfs_ordering for release-tests build

The helper at src/ssa/lower.rs was gated `#[cfg(debug_assertions)]` while
the unit test at the bottom of the file was gated only `#[cfg(test)]`.
Since `cfg(test)` is set in release builds with `--tests` but
`cfg(debug_assertions)` is not, `cargo build --release --tests` failed
with E0425. Removing the gate fixes the build; the body is `debug_assert!`
only, so the helper is free in release. Also drop the gate at the call
site to avoid a `dead_code` warning when the lib is built without
`--tests`.

* test(closure-capture): flip JS/TS fixtures to required-finding

The JS and TS closure-capture fixtures pinned the old broken behaviour
via `forbidden_findings: [{ "id_prefix": "taint-" }]`. The engine now
correctly traces taint through the closure boundary (env source captured
by an arrow function, sunk via `child_process.exec` inside the body), so
the formerly-forbidden finding is a true positive.

Match the Python sibling's shape — `required_findings` with
`id_prefix` + `min_count` plus a small `noise_budget` — and rewrite the
companion READMEs and the phase8_fragility_tests doc-comments from
"known gap" to "regression guard".

Verified:
- cargo test --release --test phase8_fragility_tests → 8/8 pass
- cargo test --release --lib bfs_assertion → pass
- corpus benchmark F1 = 0.9976 (TP=205, FP=1, FN=0) — unchanged
