* fix: set SPAWN_HOME in preload and add fs-sandbox guardrail test
The test preload now sets SPAWN_HOME to the sandbox directory by default,
so tests that call cmdRun/saveSpawnRecord without explicitly setting
SPAWN_HOME no longer write to the real ~/.spawn/history.json.
Add fs-sandbox.test.ts that verifies the sandbox is correctly configured
(HOME, SPAWN_HOME, XDG vars all point to temp). Update testing.md with
mandatory filesystem isolation rules.

* chore: add root bunfig.toml and fix biome formatting
Add root-level bunfig.toml with test preload so `bun test` works from
the repo root. Fix biome formatting in orchestrate.test.ts afterEach.
