REPL: add OSC 52 clipboard fallback and graceful degradation (#61151) When pressing Ctrl-S → Clipboard in REPL history search on a system without clipboard tools (xsel, xclip, wl-clipboard), a TaskFailedException stack trace was thrown. This adds: - `OncePerId{T}`: a new callable struct that caches `initializer(key)` per mutable key object via WeakKeyDict, for general-purpose per-object caching - `has_system_clipboard()` in InteractiveUtils to detect native clipboard availability per platform - OSC 52 terminal clipboard support as a fallback, with proper DA1 (Primary Device Attributes) query to detect terminal capability - Graceful degradation: when neither clipboard mechanism is available, the Clipboard option is skipped and a friendly message is shown instead of a stack trace Fixes #60145 Co-authored-by: Keno Fischer <Keno@users.noreply.github.com> Co-authored-by: Claude Opus 4.6 <noreply@anthropic.com>
