- Added internal protobuf wire codecs, message builders, and protocol definitions for Cursor and Devin providers.
- Deferred loading of OTel SDK and OTLP exporters and added bounded caches to optimize startup and lookup performance.
- Added SQLite-backed parse caching for legacy extension source analysis and streaming file chunk parsing for changelogs.
- Added support for rendering context usage overflow above 100% in the status line component.
Unknown LEN fields in protobuf-es carry raw wire bytes including the
length varint (BinaryReader.skip captures it; BinaryWriter.raw replays
verbatim after the tag). The fallback for unnamed permission-query
variants wrote 'approved {}' as bare 0a 00, producing a frame the
server cannot decode (the 0a is read as a length of 16). Prefix the
payload with its length and lock the wire shape with a round-trip test.
