feat(binding): add async module initialization lifecycle

[GG-O-BP]

Summary

• extend configured npm bindings with an optional static initializer export and explicit never / on-failure retry policy while preserving scalar and array binding syntax
• add caller-owned Uninitialized / Initializing / Ready / Failed lifecycle APIs backed by gleam/javascript/promise, including shared one-flight attempts, reset/settlement behavior, Lustre effects, and React Suspense consumption
• keep generated FFI deterministic and minimal: static imports, metadata lookup, and direct initializer invocation only; no dynamic import or handwritten Promise orchestration
• add typed synchronous-start and asynchronous-rejection errors, synthetic module coverage, and English/Korean/Japanese documentation

Validation

• ./scripts/verify.sh inner glendix
  • format, check, warnings-as-errors, docs: passed
  • Bun tests: 125 passed
• mandatory pre-push ./scripts/verify.sh final
  • source/style/FFI/boundary/generated checks: passed (342 external declarations)
  • standalone consumers: glendam, glendix, mendraw, mxpak passed
  • package tests: justin_fork 5, glendix 125, mendraw 41, mxpak 121 passed
  • Glendam browser tests: 61 passed
  • widget MPK build/inspection: passed
  • Lustre browser smoke: passed
  • Mendix 11.12.0 build: BUILD SUCCEEDED
  • Mendix runtime browser smoke: passed

The local Hex API repeatedly enforced its burst rate limit, so the validation-only command wrapper retried only that exact environmental error. It did not alter product source or validation criteria.

Closes #7
