oh-my-codex v0.21.8

0.21.8 is a bugfix and compatibility release for the frozen range v0.21.7..d2e91b866d540b9e2454edb1b928a56d9bd9a30c (14 commits, 25 files, +1249/−51): Windows binary path handling, session management improvements, legacy configuration support, session export capability, and diagnostic message clarifications.

Highlights

• Windows binary path compatibility: platform-specific .exe suffix is now correctly applied to omx-runtime binary paths on Windows, resolving resolution failures on Windows platforms (#3736, #3737).
• Session management robustness: thread identity resolution for native $ralplan --advisory is improved with dedicated readPayloadSessionId helper (#3740, #3741); writeAtomic Windows EPERM errors are handled correctly (#3744, #3746).
• Legacy configuration support: support for legacy v0.21.6 AGENTS.md backup paths is restored via git rev-parse, with proper handling of linked worktrees (#3739, #3742).
• Session export capability (#3745): local sessions can now be exported as Markdown or JSON format for integration and documentation pipelines (authored by @hiSandog).
• Diagnostic improvements: warning messages for non-OMX Codex sessions are clarified (#3747, #3749).

Fixes and compatibility

• Windows path handling: apply platform-specific .exe suffix to omx-runtime binary paths (#3736, #3737); handle writeAtomic Windows EPERM errors correctly by using syncRegularFile (#3744, #3746).
• Session management: resolve native $ralplan --advisory thread identity from session_id when hook payload carries no thread field (#3740, #3741).
• Legacy backup support: support legacy v0.21.6 AGENTS.md backup path via git rev-parse (#3739, #3742); resolve absolute --git-path in linked worktrees; prefer team-state backup over legacy git-dir backup.
• Diagnostic output: clarify warning message for non-OMX Codex sessions (#3747, #3749).
