docs(parity): finalize rsync-parity docs for protocol 2.26.0

Browse Source 
Reclassify the RSYNC_COMPAT matrix after the parity-completion wave (protocol
2.23.0 -> 2.26.0): 9 already-parity rows to parity, 17 inherently non-rsync
rows to divergent, and the genuine fixes to parity, recounting to
109 parity / 25 caveat / 23 divergent of 157 rows. Add rows for --bwlimit,
--partial, --partial-dir, --no-whole-file, --inc-recursive/--no-inc-recursive,
--protect-args and --msgs2stderr; fix the documented -f/filter, -F/.rsync-filter,
empty --files-from, and --preallocate/--sparse precedence bugs; add the Parity
Completion Wave section.

Refresh README/HANDOFF/release skill/cmake-expert to protocol 2.26.0 and the
zlib/lz4 + md4/sha1/none codecs, add the CHANGELOG 2.26.0 entry, and correct
the stale --max-delete --help wording.

### Dependencies
- **zstd** — found via `find_library(ZSTD_LIBRARY zstd)`
- **zstd** — found via `find_library(ZSTD_LIBRARY zstd)` (default compression codec)
- **zlib** — found via `find_library(ZLIB_LIBRARY z)` (the `zlib`/`zlibx` codecs)
- **lz4** — found via `find_library(LZ4_LIBRARY lz4)` (the `lz4` codec)
- **OpenSSL** — found via `find_package(OpenSSL REQUIRED)` (TLS 1.2+ transport)
- **xxHash** — fetched via `FetchContent` from the upstream repository (delta transfer hashing, v0.8.3)
- **pthreads** — found via `find_package(Threads REQUIRED)`
- **C11 standard** — required
- **CMake 3.22+** — minimum version
The codec matrix (protocol 2.26.0) uses zstd/zlib/lz4 for compression and
xxHash/OpenSSL for the `xxh128`/`xxh3`/`xxh64`/`md5`/`md4`/`sha1` checksums
(`none` needs no library); both codec families are negotiated per transfer.
## Conventions
- Use `file(GLOB ...)` for source collection (existing pattern).
- All targets link `Threads::Threads`, `${ZSTD_LIBRARY}`, `OpenSSL::SSL`, `OpenSSL::Crypto`, and `xxhash`.
- All targets link `Threads::Threads`, `${ZSTD_LIBRARY}`, `${ZLIB_LIBRARY}`, `${LZ4_LIBRARY}`, `OpenSSL::SSL`, `OpenSSL::Crypto`, and `xxhash`.
- Include directories: `src/shared`, `src/server`, `src/client`, `tests` (for test target).
- Sanitizer support: pass `-DSANITIZER=address`, `-DSANITIZER=thread`, or `-DSANITIZER=undefined` to cmake (live option in CMakeLists.txt).
- Build with `cmake -B build -S . && cmake --build build -j$(nproc)`.
