<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Low Risk**
> Low risk: changes are limited to the E2E test harness and smoke specs,
mainly improving WebSocket teardown/port release to avoid CI port
collisions. Main downside is reduced coverage due to multiple smoke
suites being temporarily skipped.
> 
> **Overview**
> **Improves E2E WebSocket teardown to avoid port collisions.**
`LocalWebSocketServer` now optionally tracks a `ResourceType` and always
releases its `PortManager` allocation when stopping (including when the
server was never started, and via a `finally` to guarantee cleanup on
errors). `withFixtures` now constructs the account-activity WebSocket
server with `ResourceType.ACCOUNT_ACTIVITY_WS` so this release happens.
> 
> **Unblocks CI by skipping failing smoke tests.** Several smoke specs
(native send, EIP-7702 gas fee token flows, perps liquidation, and snap
tests) are switched to `describe.skip` with comments pointing to the
tracking thread.
