v0.181.0: Slash commands while the agent runs, MCP OAuth resource override, and subagent and Git fixes

New features

- Slash commands while the agent runs - Slash commands now work during an active agent turn, so you no longer have to wait for it to finish
- MCP OAuth resource override - MCP server configs accept a resource field to send a different OAuth resource indicator, or omit it entirely

Improvements

- Subagent delegation - The agent now delegates to subagents more selectively when using OpenAI models
- Subagent results - The agent reuses a subagent's report instead of re-reading the files it already covered, making follow-up work faster

Bug fixes

- Git index lock - Checkouts now retry when another process is holding the Git index lock instead of failing
- BYOK models - Bring-your-own-key models are now scoped to the selected computer (app)
