spec(fb-35): verbatim fetch — design
`kebab fetch chunk|doc|span` 신규 subcommand + MCP `kebab__fetch`
tool. wire = `fetch_result.v1` (kind discriminator).
source = CanonicalDocument / chunks.text 정규화된 markdown (raw
bytes 미노출). chunk mode `--context N` = ordinal ±N. doc/span
mode = fb-34 budget 재사용 (chars/4). PDF/audio span 은
`error.v1.code = span_not_supported` 거절.
신규 error codes: chunk_not_found / doc_not_found /
span_not_supported / invalid_input. fb-34 StructuredError
wrapper 재사용.
