Walkthrough

Multiple files have debug logging statements and commented-out code removed, with no functional behavior changes. Additionally, the global ASSERT function is moved into a nested DEBUG namespace under a development condition, changing its public access pattern from globalThis.ASSERT to globalThis.DEBUG.ASSERT.

Changes

Cohort / File(s)	Summary
Debug logging cleanup src/bake/bun-framework-react/server.tsx, src/bun.js/bindings/libuv/generate_uv_posix_stubs.ts, test/harness.ts	Removed inactive console logging statements including commented error logs, debug logs of intermediate parsing steps, and trace statements. No control flow or error handling changes.
Debug API restructuring src/bake/debug.ts	Moved ASSERT function from top-level globalThis into a nested globalThis.DEBUG.ASSERT namespace under IS_BUN_DEVELOPMENT condition. Assertion logic remains unchanged but public API surface changes.
Commented code and comment removal src/runtime.bun.js, src/sql/mysql/MySQLTypes.zig	Removed a TODO comment referencing bundle_v2.js duplication and deleted placeholder commented-out Decimal type declarations. No active logic changes.
