Merge remote-tracking branch 'origin/master' into codex/disable-telemetry-default

Resolve three conflicts:

- packages/bundle/base/tests/base.spec.ts: keep both assertion sets — this
  branch's telemetry-otel mode expression and master's subagent rows plus
  manifest dependencies.
- packages/session/session-telemetry-otel/tests/otel.spec.ts: keep master's
  per-mode sharing disclosure test, but select FULL explicitly instead of
  relying on an omitted mode, because the default is now DISABLED; the
  default-construction test keeps asserting disabled delivery and gains a
  case pinning that an omitted mode reports 'disabled' sharing.
- scripts/snapshots/translation-prompt-v4/request-response.expected.json:
  re-recorded from the merged READMEs rather than hand-merging the embedded
  document text.
