Bug Report: hermes -z one-shot flag availability is inconsistent across Hermes versions

Description

The hermes -z flag (for one-shot queries without entering interactive mode) is available in some Hermes versions but not others. Some versions require hermes chat -q instead. This inconsistency causes scripts and helpers that rely on one-shot invocation to break depending on the installed Hermes version.

Observed Behavior

• On some versions: hermes -z "prompt" works
• On other versions: hermes -z produces unrecognized arguments error
• hermes chat -q "prompt" is more consistently available across versions

Impact

• Scripts must include version-detection logic before every one-shot invocation
• The second_opinion.py helper and other tooling had to implement fallback logic to detect which syntax works
• New users following documentation with the wrong version get confusing errors
• The --timeout flag also has inconsistent support (accepted by some subcommands but not hermes chat -q)

Suggested Fix

Option A — Unify: Make hermes -z and hermes chat -q both accept equivalent flags across all versions, or deprecate one in favor of the other.

Option B — Document: Add a prominent note in hermes --help and the Hermes documentation about which one-shot invocation syntax is supported in the current version, and what the recommended cross-version approach is.

Option C — CLI helper: Add a hermes detect-invocation command that prints the correct one-shot syntax for the current version, so scripts can auto-detect without string-parsing --help output.
