chore(deps): update protobufjs to v8

[kilo-code-bot]

Summary

• Bumps protobufjs from 7.5.4 to ^8.0.3 via a pnpm.overrides entry in the root package.json.
• protobufjs is not a direct dependency of any package in this repo; it is only pulled in transitively by @opentelemetry/otlp-transformer, which uses it to encode/decode OTLP protobuf payloads against its own pre-generated descriptors.

Why the v8 breaking change does not impact us

The only breaking change in protobufjs v8.0.0 is the addition of Edition 2024 support in the .proto parser. That affects code paths where .proto files are parsed at runtime (or via pbjs/pbts) to build Root/Type descriptors.

We do not do that anywhere:

• No package in this repo declares a direct dependency on protobufjs.
• No .proto files are shipped or loaded at runtime.
• The sole consumer, @opentelemetry/otlp-transformer, uses bundled, statically generated OTLP descriptors and only uses protobufjs for wire-format encode/decode, which is unchanged by the Edition 2024 work.

In addition to the edition work, v8 rolls up the 7.5.5 / 7.5.6 input-hardening and security fixes, so this is a safe upgrade for our usage.

Verification

• grep -rn protobufjs across package.json files confirms no direct dependents; the only reference is the pnpm.onlyBuiltDependencies allowlist entry (build-script approval, not a dep).
• pnpm-lock.yaml shows protobufjs@7.5.4 only under @opentelemetry/otlp-transformer.
• Lockfile regeneration (pnpm install) intentionally skipped in this commit per the request; will be applied together with CI/typecheck in a follow-up run before merge.

Reviewer Notes

• The override uses ^8.0.3 so we pick up 8.x patch releases automatically.
• pnpm install still needs to be run to regenerate the lockfile before this can land — flagging so reviewers are not surprised by the missing lockfile update.
• If any future service starts parsing .proto files at runtime, that code should be reviewed against the Edition 2024 parser changes, but nothing today does.
