#### (Copies commits from #26447)
## Summary
- Add a global `--retry <N>` flag to `bun test` that sets a default
retry count for all tests (overridable by per-test `{ retry: N }`). Also
configurable via `[test] retry = N` in bunfig.toml.
- When a test passes after one or more retries, the JUnit XML reporter
emits a separate `<testcase>` entry for each failed attempt (with
`<failure>`), followed by the final passing `<testcase>`. This gives
flaky test detection tools per-attempt timing and result data using
standard JUnit XML that all CI systems can parse.
## Test plan
- `bun bd test test/js/junit-reporter/junit.test.js` — verifies separate
`<testcase>` entries appear in JUnit XML for tests that pass after retry
- `bun bd test test/cli/test/retry-flag.test.ts` — verifies the
`--retry` CLI flag applies a default retry count to all tests
## Changelog
<!-- CHANGELOG:START -->
- Added `--retry <N>` flag to `bun test` to set a default retry count
for all tests
- Added `[test] retry` option to bunfig.toml
- JUnit XML reporter now emits separate `<testcase>` entries for each
retry attempt, providing CI visibility into flaky tests

## Summary
- Fixed documentation that incorrectly claimed you could use `[env]` as
a TOML section to set environment variables directly
- The `env` option in bunfig.toml only controls whether automatic `.env`
file loading is disabled (via `env = false`)
- Updated to show the correct approaches: using preload scripts or
`.env` files with `--env-file`
## Test plan
- Documentation-only change, no code changes
