Extract the envelope deserialization pipeline from cmd/scan_code.go into file_format.UnmarshalEnvelope, which parses the header, selects the encoder via the new envelope.NewEncoder factory, unwraps, and unmarshals the binary container. The envelope now handles gzip compression internally: Wrap stores the payload gzipped only when it is smaller, recording CompressionType in a new header bit, and Unwrap decompresses transparently. container_pdf.go no longer pre-compresses before wrapping.
…implementations Replace the package-private compress/decompress helpers with a Compressor interface selected by CompressionType via NewCompressor. RawCompressor is a no-op pass-through; GzipCompressor applies gzip BestCompression on compress and transparently decompresses on read. Unwrap now dispatches through NewCompressor instead of special-casing gzip.

In `@internal/file_format/envelope/compression.go`:
- Around line 93-106: Update GzipCompressor.Decompress to enforce a maximum
uncompressed container size: define or reuse the established maximum-size
constant, read at most that limit plus one byte from gz, and return an error
when the extra byte indicates the limit was exceeded. Preserve the existing
reader-creation, read, close, and successful output behavior for data within the
limit.
In `@README.md`:
- Around line 282-283: Update the envelope header documentation near the
`ParseHeader` description to state the exact `headerAlphabet` accepted by
`ParseHeader`, or explicitly identify the field as using a non-Base32 alphabet;
do not describe `0-9A-Z` as Base32.
- Line 288: Update the fenced code block in the README by adding a blank line
before the opening fence and specifying a language identifier such as text on
that fence, resolving MD031 and MD040.

In `@AGENTS.md`:
- Around line 36-37: Clarify the version references in the documentation around
internal/file_format and its container decoding behavior: distinguish any legacy
v3 protocol from the current binary container format version 5, or update the
references to v5 where they describe the active wire-format contract. Keep the
envelope format details and README synchronization guidance unchanged.
