fix: restore update-typescript-go workflow

[xesrevinu]

Summary

Fix the automatic update-typescript-go workflow after the latest upstream typescript-go update.

This PR:

• refreshes _patches/001-cmd-tsgo-main.patch against the current upstream cmd/tsgo/main.go
• updates the typescript-go submodule to ee4225a856389fc94c8ce4a5fd9af771dbbc2c0b
• refreshes generated shim output for the upstream API changes
• syncs flake.nix / flake.lock with the updated upstream commit
• hardens _tools/update-flake-vendor-hash.sh for local/staged submodule refreshes and empty NIX_BUILD_ARGS

Why

The scheduled workflow started failing in pnpm setup-repo --ci because _patches/001-cmd-tsgo-main.patch no longer applied after upstream added internal/core imports and core.ApplyDebugStackLimit() to cmd/tsgo/main.go.

Validation

Ran locally:

• pnpm setup-repo --ci
• pnpm check
• pnpm test
• nix build .#effect-tsgo

pnpm lint still reports pre-existing modernize diagnostics unrelated to this change.
