chore(deps): bump rescript-bindgen to ^1.4.0-beta.2 + regenerate for blend-design-system@0.0.38-beta.1

[jagguji]

Summary

Bumps @juspay/rescript-bindgen to ^1.4.0-beta.2 and @juspay/blend-design-system to 0.0.38-beta.1, regenerating bindings with both fixes applied. Supersedes #144, which regenerated against the same blend version but with rescript-bindgen@1.4.0-beta.1 — before these fixes existed.

Why not just #144

1.4.0-beta.1 doesn't crash on this blend version, but its output has a real quality problem: blend 0.0.38-beta.1 introduces ComponentTokenOverrides (a DeepPartial<ComponentTokenType> wrapper for ThemeProvider's token-override prop), which exposes a large CSS-property union (csstype Property.*, every CSS global keyword + every named color) through a second generic path. On 1.4.0-beta.1 that produces constructor names over 2,400 characters long (e.g. ...MozInitialOrInheritOr...OrAliceblueOrAntiquewhiteOr...) — technically correct, but unusable, and it lands directly in the type surface app developers touch when overriding tokens.

1.4.0-beta.2 fixes this and one more thing along the way:

• finalizePublicIds no longer hard-crashes on a public-identity collision. An intermediate main build of bindgen (with the new name-freezing identity system) actually crashed with zero output on this exact blend version — SEARCH_INPUT's and MODAL's rangeDay token configs collide onto one ThemeProvider.rangeDay projection, and the old code treated any such collision as a hard abort. It now degrades to a shape-disambiguated id and warns instead.
• Anonymous @unboxed union names are capped at 64 chars (readable prefix + shape hash) instead of enumerating every member. The 2,453-char name above is now 44 chars, e.g. mozInitialOrInheritOrInitialOrRevertEtc1mkx8.

Verification

• _REPORT.md: 235 components · 226 usable · 9 need review · 0 broken — identical component classification to chore(sync): regenerate bindings for @juspay/blend-design-system@0.0.38-beta.1 #144, same 9 components flagged for review, 0 fidelity loss (0 loosely-typed).
• Longest generated identifier: 114 chars (a legitimate descriptive name, TextArea's omitted-HTML-attributes type), down from 2,453+.
• npm run build → 320 modules compiled, 0 errors.
• Regeneration is deterministic — ran twice from a clean slate, byte-identical output.
• No previously-fixed defect reappeared: no orphan JsFn.res, no unreferenced shared-type modules; the one new module (ChartsSharedTypes.res) matches a documented SCC-merge dissolution, not a regression.

Reviewer checklist

• npm run build is green (CI will block if not)
• src/_REPORT.md shows 0 broken components; skim any flagged/loose props
• Diff looks sensible — especially prop/variant renames that could break downstream consumers
• Version = blend version (set automatically via --set-version)
