[codex] Update Codex Token Usage to 0.1.3

[kokotao]

Summary

Updates the Codex Token Usage market script to version 0.1.3.

This release fixes session-scoped rendering and restores the historical per-call aggregation behavior. The important correction in 0.1.3 is that Codex token_count.total_token_usage is treated as cumulative session/turn context information, not as a single model call. Per-reply input/output totals and 调用 N 次 are again derived from repeated last_token_usage / model usage updates entering the turn call list.

Details

• Scope token usage metrics by active conversation/thread id.
• Clear stale badges when switching to a conversation with no recorded metric.
• Restore cached metrics only for the active conversation.
• Show the running badge only after a Codex API request starts, not while typing or pressing Enter.
• Restore historical call aggregation by using last_token_usage as the per-call token usage source.
• Avoid treating cumulative total_token_usage as a single model call, which made call count stick at 1 and token totals look wrong.
• Always show completed call count, including 调用 1 次.
• Bumps codex-token-usage metadata to 0.1.3 and refreshes SHA-256.

Validation

• Source script tests passed in codex-token-usage-script: npm test -> 19/19 passing.
• Source script metadata validation passed: npm run check:index.
• Local installed Codex++ user script copies were synced and byte-compared against the source script.
• Market index.json SHA was validated against scripts/codex-token-usage.js.
• Market script was byte-compared against the verified source script.
