  1. feat: serveCar implements ?format=car

    This is PoC implementation that returns CAR as a chunked stream.
    It does not set cache-control nor it has content-length.
    
    TBD if we want/can have these things.

  1. feat(gw): ?format= or Accept HTTP header

    - extracted file-like content type responses to separate .go files
    - Accept HTTP header with support for application/vnd.ipld.* types
      (TBD, we did not register them yet, so for illustration purpose only)

  2. refactor: unixfs_get_latency_seconds

    Include block and car in unixfs_get_latency_seconds for now,
    so we keep basic visibility into gateway behavior until better metrics
    are added by #8441

  3. fix: use .bin for raw block content-disposition

    .raw may be handled by something, depending on OS, and .bin
    seems to be universially "binary file" across all systems:

  5. test: t0118-gateway-car/carv1-basic.car

    This test uses official CARv1 fixture from
    https://ipld.io/specs/transport/car/fixture/carv1-basic/
    
    The CAR has two dag-cbor roots, and we use one of them, which represents
    a nice DAG with both dag-cbor, dag-pb and raw blocks

  5. refactor: prefix cleanup and readable paths

    - removed dead code after X-Ipfs-Gateway-Prefix is gone
      (#7702)
    - escaped special characters in content paths returned with http.Error
      making them both safer and easier to reason about (e.g. when invisible
      whitespace unicode is copied)
