Replaces the copy-pasted bearer-auth + X-Browse-Gen + req.json().then().catch()
boilerplate on /internal/grant and /internal/revoke with a single
internalHandler<T>(req, fn) wrapper. Future /internal/* routes added by the
v1.44 long-lived-sidebar work (/internal/lease-refresh, /internal/restart)
land as one-liners using the same helper. Pure refactor; no behavior change.
/internal/healthz stays on the bare checkInternalAuth gate because it's a
GET with no JSON body to parse — the helper's body-parse path would 400 it.
* browse/src/terminal-agent.ts — new internalHandler<T>; /internal/grant
+ /internal/revoke routed through it.
* browse/test/terminal-agent-internal-handler.test.ts — static-grep
tripwire that fails CI if the helper goes away or either of the two
refactored routes regresses to the old inline pattern.
