v2.6.34 — dependency updates and a batch of read/hook fixes

Dependency updates plus fixes to dead --kind, the compress gate, hint stats, secret redaction and image shrinking.

Highlights:

• dead --kind no longer rejects real symbol kinds as typos. The list of known kinds had drifted 27 kinds behind the language adapters, so dead --kind var answered "Unrecognized kind" and suggested variable, a different kind. It is now built so it cannot drift again.
• A trailing 2>&1 no longer turns off command compression. Commands ending that way, which is most of the high-output ones, were skipping compression entirely.
• Three private key formats and Slack app-level tokens are now redacted before anything is written to the cache.
• The image quality setting works again after a file has been read once.
• Dependencies updated, including csv-parse 7.0.2, which fixes a prototype replacement reachable through the columns option.
• The VS Code extension now compiles against the same editor version it says it supports.
