vendor(unrar): add unrar 7.20.1 (RARLab source, opello mirror)

New RAR engine for v1.9, replacing dmc_unrar 1.7.0. dmc_unrar only dispatches RAR5 compression version 5 (switch(file->version) case 0x5000); WinRAR 6.x/7.x writes version 6 -> DMC_UNRAR_FILE_UNSUPPORTED_VERSION -> user-facing "corrupt archive" on real v6 archives (diagnosed 2026-09-05 from a v6:8M:m0:m3 test file). unrar 7.20.1 natively supports v6, encrypted and multi-volume RAR. Vendored into third_party/unrar7/ (new dir) so the tree stays buildable while src/rar_extract.c still references the dmc facade. Contents are a verbatim copy of opello/unrar @97e1780 (159 files, v7.20.1) plus two project files: - unrar_c_api.h (C facade shim: platform types + dll.hpp re-export) - VENDORED.md (source pin, build model, license notes) Build model verified on host (MinGW g++ 16.2, Windows): - all 49 UnRARDll.vcxproj sources compile with -std=c++17 -DRARDLL -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE - links + runs: RARGetDllVersion() = 9 (smoke binary in .build/, ignored) - Windows link additionally needs -lpowrprof License: UnRAR freeware license (not GPL) - free to use for handling RAR archives; cannot be used to build a RAR-compatible archiver. THIRD_PARTY_NOTICES update lands with the engine swap commit. Next (v1.9 work items): engine swap in rar_extract.c, Makefile .cpp rules, fixtures + host tests, frontend password/multi-volume, then ELF build.

+# Vendored: unrar 7.20.1 (RARLab UnRAR source)
+
+Replaces `dmc_unrar` (see git history under `third_party/unrar/`) as the RAR
+engine. This is the official Alexander Roshal UnRAR source, packaged on
+GitHub by opello for easier vendoring.
+
+## Source
+- Upstream: https://github.com/opello/unrar — commit `97e1780310`
+  ("v7.20.1: Extracted from https://www.rarlab.com/rar/unrarsrc-...", 2025-10-30)
+- Version: 7.20.1 (see `version.hpp`: RARVER_MAJOR 7, RARVER_MINOR 20, BETA 1,
+  built 2025-10-28)
+- Mirror of RARLab https://www.rarlab.com/rar_add.htm — this directory is a
+  verbatim copy of the upstream tree (159 files), no modifications except the
+  additions listed below.
+
+## What this enables that dmc_unrar could not
+- **RAR5 compression version 6** (WinRAR 6.x / 7.x archives, "v6:" algorithm
+  string). dmc_unrar 1.7.0 only dispatched `0x5000` (v5) in
+  `dmc_unrar_file_unpack`, so any WinRAR 6+ archive hit
+  `DMC_UNRAR_FILE_UNSUPPORTED_VERSION` and surfaced as "corrupt archive".
+- **Encrypted RAR** (headers and/or entries) — password via `RARSetPassword`.
+- **Multi-volume RAR** (`.partNN.rar` chains) — via open-mode + volume
+  callback handling.
+- RAR4 (all sub-versions) continues to work.
+
+## Build model
+Compile the upstream DLL source set as a **static library**, define
+`-DRARDLL` (suppresses `rar.cpp`'s `main()` via `#if !defined(RARDLL)`).
+
+Source set (49 .cpp, matching `UnRARDll.vcxproj` ClCompile list):
+archive arcread blake2s cmddata consio crc crypt dll encname errhnd extinfo
+extract filcreat file filefn filestr find getbits global hash headers isnt
+largepage match motw options pathfn qopen rar rarpch rarvm rawread rdwrfn
+rijndael rs rs16 scantree secpassword sha1 sha256 smallfn strfn strlist
+system threadpool timefn ui unicode unpack volume
+
+Compile flags:
+- `-std=c++17 -DRARDLL -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE`
+- PS5 (`prospero-clang++`): the toolchain defaults to `-stdlib=libc++`
+  (FreeBSD-style sysroot; there is no GNU libstdc++). No explicit `-lc++`
+  needed. `_UNIX` is defined by the platform headers.
+- Host tests (Windows/MinGW `g++`): libstdc++ default is fine.
+- Windows link needs `-lpowrprof` (SystemSuspend in `system.cpp`);
+  `SetSuspendState` is referenced only on `_WIN_ALL`.
+
+The upstream C API (`dll.hpp`) is C-compatible (extern "C" + plain C
+structs). C translation units include `unrar_c_api.h` (platform shim +
+re-export of the entry points used by `src/rar_extract.c`), never the unrar
+C++ headers.
+
+## Additions in this directory (not upstream)
+- `unrar_c_api.h` — WFM facade shim (see file header).
+- `VENDORED.md` — this file.
+
+## License
+UnRAR freeware license (`license.txt`): free to use in any software to
+handle RAR archives; may NOT be used to build a RAR-compatible *archiver* or
+re-create the RAR compression algorithm. Full text must stay with the
+source. This replaces the GPL-2.0 dmc_unrar notice in THIRD_PARTY_NOTICES.

+
+* We used "Screaming Fast Galois Field Arithmetic Using Intel
+  SIMD Instructions" paper by James S. Plank, Kevin M. Greenan
+  and Ethan L. Miller to improve Reed-Solomon coding performance.
+  Also we are grateful to Artem Drobanov and Bulat Ziganshin
+  for samples and ideas allowed to make Reed-Solomon coding
+  more efficient.
+
+* RAR4 text compression algorithm is based on Dmitry Shkarin PPMII
+  and Dmitry Subbotin carryless rangecoder public domain source code.
+  You can find it in ftp.elf.stuba.sk/pub/pc/pack.
+
+* RAR encryption includes parts of public domain code
+  from Szymon Stefanek AES and Steve Reid SHA-1 implementations.
+
+* With exception of SFX modules, RAR uses CRC32 function based
+  on Intel Slicing-by-8 algorithm. Original Intel Slicing-by-8 code
