refactor: Simplify trivial code patterns

[ChihweiLHBird]

• Use != instead of not x == y in websocket connection_lost
• Use not expr instead of False if expr else True in CLI arg parsing
• Use tuple literals instead of tuple([...]) for CancelledErrors
• Return boolean expression directly instead of if ...: return True; return False in WorkerProcess._add_config

[Copilot]

Pull request overview

Refactors a handful of small boolean/tuple patterns to more direct and idiomatic Python forms across worker process configuration detection, WebSocket lifecycle handling, CLI inspector argument parsing, and compat utilities.

Changes:

• Return boolean expressions directly instead of multi-branch if/return patterns.
• Replace not x == y with x != y in WebSocket connection_lost.
• Simplify tuple construction and boolean negation in compat/CLI code paths.
