Merged open-source fixes

• PostHog: React Native stack traces kept when a frame has an undefined key (posthog-js#5290); forum threads render when an edit has no author (posthog.com#20989); failed job submissions now record why (posthog.com#20986)
• Roboflow Inference: the CLI says what to do when the server is unreachable (inference#3129)
• Ledger device Rust SDK: legacy IO sends the status word in the buffer that is actually transmitted (commit 02341a8)
• CPython (under review): two _pyio bugs reported, with fixes (#161273, #161274)

Research

Systematic crypto research with pre-registered tests, placebo and random-side twins, and deflated Sharpe. The strategy is private; a public repo with the testing methods is coming.
