Sanitize shadowCallRewrittenFrom before retaining the entry.

appendUsageEntry sanitizes this field before writing usage.jsonl, but addRequestLog retains the original entry first at src/server/request-log.ts:337. /api/logs then spreads retained entries through requestLogDto, so an exported addRequestLog caller can bypass sanitizeLogMetadataString and expose control characters or secret-shaped text. Sanitize a copy before retention and reuse it for persistence. Add a direct-call regression test in tests/request-log.test.ts.

sanitize shadowCallRewrittenFrom on a copied entry before retaining it, and
reuse that sanitized entry for persistence so /api/logs cannot expose
unsanitized values; add a direct-call regression test in request-log.test.ts
covering control characters and secret-shaped text.

## Usage accounting

`src/usage/log.ts` writes append-only JSONL to `~/.opencodex/usage.jsonl` with file mode `0o600`.
An opt-in shadow-call rewrite persists the bounded, redacted original helper model as
`shadowCallRewrittenFrom`, so helper traffic remains identifiable after restart without storing
request content or inferring a helper subtype from timing.
`src/usage/summary.ts` turns that file into the `/api/usage` shape — totals, daily zero-filled
grid, model and provider breakdowns, and `measured / reported / unreported / unsupported / estimated` counts.
A Codex-surface response also includes an `accounts` breakdown keyed by the stable non-PII
