/**
* Extract NEW i18n keys created by subagents from git diff.
*
* For each modified .tsx file, walk the unified diff and pair "-" lines
* (containing literal English text) with their following "+" lines
* (now using `t("key")`). When we find a stable pairing, record the key
* and its original English value.
*
* The output is a per-namespace map ready to merge into en.json.
