* fix(cli): stop quietly when the stdout reader closes early
`rea ... | head` crashed once head closed the pipe. TOON and YAML output
raised an unhandled EPIPE 'error' event with a Node stack trace. JSON
output reported {"code":"UNKNOWN","message":"write EPIPE"} on stderr.
Both exited 1, as if the analysis had failed.
The CLI entry point owns process.stdout, so it now treats EPIPE as the
reader declining the rest of the output. It stops writing, suppresses
the failure report and exits 141 like a SIGPIPE-terminated writer, also
when Incur exits through its own failure path. Other stdout errors are
handled as before.

* fix(cli): guard mcp doctor output and cover midstream reader closure
The closed-reader guard was only installed for ordinary CLI commands. As a
result `rea mcp doctor | head` still crashed on EPIPE. The guard now lives
in one entry-point function shared by both CLI branches; MCP stdio keeps
its own lifecycle.
The tests now also close the reader after the first chunk of a 4 MiB
streamed JSON result, so later writes in writeJsonOutput are covered.
