Claude Code v2.1.261–263: inline output limits up to 128K chars, Remote Control hardening

Following Wednesday's 2.1.260, v2.1.261 (Sep 4) adds `/skill-doctor` context-cost diagnostics, new `bashOutputMaxChars`/`taskOutputMaxChars` settings raising inline command output up to 128K chars, `--append-subagent-system-prompt-file`, an organization-policy line in `/status`, a broader dangerous-`rm` safety prompt, and VS Code MCP-server management from the IDE; it also fixes ~30 issues across Remote Control, resume fidelity, Bedrock/Vertex setup and streaming. v2.1.263 (Sep 6) is a follow-up bugfix and reliability release.
