fix(acp): resolve bypass mode for claude-agent-acp

The _BYPASS_MODE_MAP only matched "claude-code" but the actual agent
name is "@zed-industries/claude-agent-acp", which doesn't contain that
substring. Add "claude-agent" as an additional key so the mode correctly
resolves to "bypassPermissions" instead of falling through to the
default "full-access" (which claude-agent-acp rejects).
