fix: rename browse E2E test file to prevent pkill self-kill

The Claude agent inside browse E2E tests sometimes runs
`pkill -f "browse"` when the browse server doesn't respond.
This matches the bun test process name (which contains
"skill-e2e-browse" in its args), killing the entire test runner.

Rename skill-e2e-browse.test.ts → skill-e2e-bws.test.ts so
`pkill -f "browse"` no longer matches the parent process.
