Diego Rodrigues de Sa e Souza 2ce64e8f38 refactor(executors): extract pure EventStream framing from kiro (#6018)
Extract the pure AWS EventStream binary framing (ByteQueue, CRC32 table + crc32,
TEXT_ENCODER/TEXT_DECODER, KIRO_VERIFY_FULL_CRC, parseEventFrame, EventFrame type)
verbatim into the self-contained leaf kiro/eventstream.ts (local JsonRecord alias to avoid
a cycle). Host imports back the 3 it uses (ByteQueue, TEXT_ENCODER, parseEventFrame).

Host 943 -> 758 LOC. Byte-identical bodies (verbatim 145/145), leaf has zero host imports
(no cycle). Auth/token-refresh/streaming-state/executor class untouched; the test-imported
flushBufferedToolArgs/resolveKiroRegion/kiroRuntimeHost stay exported on the host. Adds a
split-guard; consumer tests stay green (executor-kiro 9, kiro-tool-args-streaming 7,
kiro-iam-region 10).
