fix(kernel): stop asserting the user's OS in advisor startup context

[adampog]

What a user gets

Before: the kernel advisor's startup context stated "The user is on macOS", so on Linux hosts the advisor began with a wrong picture of the machine. After: it says OpenRig runs on macOS and Linux, and to check the host when it matters.

How you verified it

On b5a9deaf (current main) plus this commit: a 4-line wording change in packages/daemon/specs/rigs/launch/kernel/agents/advisor/lead/startup/context.md. npm run lint passed. There's no automated test for this text. On a Linux host, the advisor seat opened by flagging the macOS assumption as wrong, which is what prompted the change.

Not run: the full npm test and npm run test:ui.

Anything you were unsure about

Whether you'd prefer the kernel to detect the OS and state it, rather than staying platform-neutral. I kept it neutral as the smaller change.

• One concern per PR; no version bump; no CHANGELOG.md edit
• Tests added or updated where the change is testable
• I listed the checks I ran, their results, and any checks I could not run

Made with an agent team (Claude Code and Codex), with an independent QA pass before submission.

📝 Walkthrough

Walkthrough

The startup context now states that OpenRig runs on macOS and Linux. It no longer assumes a specific host OS and advises checking the host OS when relevant. The Claude Code and/or Codex authentication assumption remains.

Before / after behavior

• observed — Modified behavior in packages/daemon/specs/rigs/launch/kernel/agents/advisor/lead/startup/context.md: The context retains the assumption that the user has Claude Code and/or Codex authenticated, but replaces the macOS-only assumption with macOS and Linux support and guidance to check the host OS when it matters.

Thanks, @adampog. On current main, the kernel advisor's startup context does say "The user is on macOS". We've approved the CI runs, and it's with the team for review. Your question about detecting the OS rather than staying neutral is part of that review.

[openrig-review]

Approved at af0e03c. Text only: the kernel advisor's startup context no longer tells the agent the user is on macOS. It now says OpenRig runs on macOS and Linux and to check (for example uname -s) when it matters. That's better than having the kernel detect the OS: the agent can check at the moment it needs to. All 8 required checks pass. Thank you.

Merged, thanks @adampog. The kernel advisor no longer assumes macOS, and checks the host when it matters. On your question, we kept it neutral as you wrote it rather than detecting and stating the OS. It's on main and isn't in a release yet.
