chore(#9): clippy --workspace -D warnings = 0 + Bun crash investigation

[gHashTag]

Two tasks in priority order

P0 — Bun C++ panic (15 min)

During input tests: panic(main thread): A C++ exception occurred

This is likely a CDP connection race or Bun version issue in trios-mcp-bridge tests.

cd packages/browseros-agent/apps/trios-mcp-bridge
bun test 2>&1 | grep -A5 'panic\|exception\|C++'
# Identify which test triggers it
# Fix: add teardown/cleanup or increase CDP timeout
bun test  # Must be 69/69 with no panics

P1 — Clippy workspace (15 min)

cd /Users/playra/trios
cargo clippy --workspace -- -D warnings 2>&1
# Fix all unused imports in trios-git + trios-gb
cargo clippy --workspace -- -D warnings
# Must be 0 warnings
cargo test --workspace
# Must be green

P2 — save_pdf 3/4 (30 min) — BrowserOS issue
