Adds tests/background/sw-bundle-import.test.ts that loads the built SW
chunk under SW-simulated globals (Buffer/process/window/document stripped)
via a spawned Node child process. Pins the orchestrator-side gap that
caused Plan 01-08's SW init crash: the prior deps test only checked
SOURCE packages under default Node globals, never the bundled output, so
Vite/Rollup's CJS-interop bug (tree-shaking the `ebml` package while
leaving a dangling `{tools:f}=Pc` destructure against an empty Pc) went
undetected until operator empirical smoke.
RED against HEAD aabbd0c — failure surfaces the exact production error
("Cannot read properties of undefined (reading 'readVint')"), proving
the test is a true regression gate, not a tautology.
Also rewrites .planning/debug/01-08-sw-incompatibility.md to reflect the
actual root cause (Vite/Rollup CJS interop) rather than the orchestrator's
initial falsified hypothesis (new Function + Buffer globals — disproven
by Node simulation showing the throw fires at module-init line 12:33809
before any CSP-eval or Buffer-ref code path executes).
Full vitest: 60 passing + 3 RED (this gate + the 2 pre-existing Task 5
fixture-dependent duration tests). No regressions.
Per feedback-pre-checkpoint-bundle-gates.md (auto-loaded memory): any
future plan executor whose work surfaces a SW must run this test before
any operator-empirical checkpoint.
