From the narrow Codex confirmation: provider, KSEI, and manifest text
still reached the terminal through error messages (a Yahoo error
description, a manifest's `kind`), idx-core diagnostics, the ownership
heading's ticker code and Bing date, the technical heading and
comparison symbol, and printed paths. Sanitize where every error
(emit_error) and every diagnostic (runtime) is printed instead of at each
caller, plus the remaining direct prints. terminal_safe moves to
idx_core::text so the runtime can use it; the CLI re-exports it.
