* fix(codex): full-auto approvals survive relay unavailability, typed failure classification, usage line after fallback
- full-auto (approvalPolicy never + danger-full-access) exec approvals no
longer get declined when the native hook relay is unreachable BEFORE
invocation; an invoked relay's explicit deny, malformed output, or nonzero
exit still fails closed (#107447)
- startup timeout/abort and request-timeout classification use typed error
discriminants instead of message prose; EPIPE detection walks error causes;
compaction keeps the message-based thread-not-found gate because codex-rs
exposes no dedicated code (its own contract test asserts the message) and
the generic -32600 would over-match unrelated invalid requests (#99270)
- /status keeps the Codex usage/quota line for sessions whose persisted
agentHarnessId is codex even when the effective runtime fell back to
OpenClaw Default; never-codex sessions remain excluded (#105184)
* chore(codex): keep startup error reason type module-local
