chore: fix root typecheck command for turbo packages

[Dexploarer]

Summary

• Remove the unsupported --filter='!./vendor/*' from the root typecheck script so turbo runs across all workspace packages as intended.

Validation

• bun run --cwd packages/auth typecheck
• bun run --cwd packages/sqlit typecheck
• bun run --cwd apps/wallet typecheck
• bun run --cwd apps/documentation typecheck
• bun run --cwd packages/bridge typecheck
• bun run typecheck:rust
• bunx pyright packages/training/python apps/dws/api (pre-existing unrelated errors remain)
