Claude Fable 5 c2a6c95f15 appledouble: initial commit, extracted from ad-decoder

The codec module (src/appledouble.rs) lifted verbatim from ad-decoder's
working tree at extraction time — including its uncommitted entry-ID
constant additions — with only the crate-level docs rewritten. 17
in-module tests carried over and green.

AppleSingle/AppleDouble container codec: exhaustive parse, lossless build.

Extracted from ad-decoder as a shared crate. Entries decode into a BTreeMap<u32, Vec<u8>> with typed views over Real Name (3), Comment (4), File Dates (8), Finder Info (9), and Macintosh File Info (10) — everything else is preserved as raw bytes, so parse → build round trips are lossless even for entry types this crate has no opinion about. The macOS ATTR extension (arbitrary xattrs packed after Finder Info) is parsed and rebuilt.

Consumers:

ad-decoder — assertive (non-obliterative) sidecar folding onto APFS
adx — AS/AD inspection and editing
fsinspect — FUSE-side AppleDouble synthesis for Linux EA recovery
