Release 1.4.0-beta.2

[jagguji]

Cuts 1.4.0-beta.2 — six fixes since beta.1, all under the 1.4.0 line. Version bumped, [Unreleased] CHANGELOG cut with an upgrade note.

What ships

• Large numeric-literal unions generate unusable type names (v100OrV102Or…OrV511OrV1), blocking constrained-generic resolution #190 — permanent public type names + readable large-union names (introduces .bindgen-manifest.json) — headline
• Return-only generic dead end strands an orphan record in the FUNCTION path (method path is fixed) #191 — reachability sweep drops orphan records
• Speculative @unboxed classification leaks orphan shared records #178 — no orphan JsFn.res after the sweep
• finalizePublicIds hard-crashes on a public-identity collision (blend 0.0.38-beta.1 DeepPartial), aborting generation with zero output #198 / Large numeric-literal unions generate unusable type names (v100OrV102Or…OrV511OrV1), blocking constrained-generic resolution #190 follow-up — degrade a public-identity collision instead of crashing → unblocks blend 0.0.38-beta.1
• Anonymous large @unboxed union names bloat to 2000+ chars (CSS Property.* mixes in blend 0.0.38) #200 — cap bloated anonymous @unboxed union names (2,453 → readable prefix + shape hash)

Release mechanics

• package.json + package-lock.json → 1.4.0-beta.2 (verified in agreement).
• CHANGELOG [Unreleased] cut under ## [1.4.0-beta.2] — 2026-08-20 with a regenerate/manifest upgrade note.
• npm test green on main at cut; benchmark 0 WARN (all packages identical/PASS).

To publish

Merge this, then tag v1.4.0-beta.2 on the merge commit and push — publish-npm.yml derives the beta dist-tag from the version. Tag push is intentionally left to a maintainer.
