Bug Report

Summary

After upgrading from v0.18.2 to v0.19.0, the PGLite WASM crash (originally reported in #223) went from intermittent to consistently reproducible on macOS 25.3 arm64 with Bun 1.3.12. Every gbrain command that touches PGLite now fails immediately.

Regression

• v0.18.2: WASM crash was intermittent — some commands (e.g. gbrain embed --all) initialized successfully and ran to completion
• v0.19.0: WASM crash is 100% consistent — no PGLite commands work at all

Error

PGLite failed to initialize its WASM runtime.
  This is most commonly the macOS 26.3 WASM bug: https://github.com/garrytan/gbrain/issues/223
  Run `gbrain doctor` for a full diagnosis.
  Original error: Aborted(). Build with -sASSERTIONS for more info.

Steps to Reproduce

1. macOS 25.3 (Darwin 25.3.0, arm64) + Bun 1.3.12
2. Upgrade gbrain from v0.18.2 → v0.19.0 via git pull && bun install
3. Run any gbrain command: gbrain embed --all, gbrain config show, gbrain stats
4. All fail with WASM crash

Environment

• OS: macOS Darwin 25.3.0 arm64
• Bun: 1.3.12
• gbrain: v0.19.0 (commit 78ba0b5)
• PGLite: 0.4.3
