• refactor(sandbox): drive sandbox context note from unified resolver (#90)

The sandbox context note that tells sessions their bash tool calls run inside a container is now sourced from the single shared SandboxContext in src/sandbox/context.ts instead of being appended to loop prompt bodies. The unified sandbox message hook (src/hooks/sandbox-message.ts) injects it into every session whose tool calls are routed into a container — sandbox loops, their Task-tool subagents, and sessions with the host sandbox toggled on — so subagents that never see a loop prompt body still receive the container context from one point of truth.
