main() only ever read argv[1], silently ignoring any further test
names despite both the usage text and the file's own top-of-file
comment claiming "one or more of the below" was supported. Rewrote
argument handling to collect every named test (or expand "all"),
validate all names up front (bailing with the usage listing if any is
unrecognized, rather than silently running a partial set), and run
them with the same pass/fail summary "all" already used - single-test
invocations now also get the "**** Running test X ****" banner "all"
always had, for consistency.
Verified: `UnitTest.exe CLZ MathUtil Path` now runs all three (was:
silently only CLZ); a bad name reports "Unknown test: X" plus usage
and exits 1; `all` and single-name behavior otherwise unchanged.

Headless.cpp, NativeApp.cpp, and SDLMain.cpp each still hand-parsed a few
argv flags directly (mount/log/state/ignore/loglevel in headless and the
app, xres/yres/dpi/scale in SDL), duplicating and in some cases conflicting
with the shared CommandLineOptions parser. Consolidate all of it into
CmdLine.cpp/.h so there's a single source of truth, and drop the now-dead
remain_argc/remain_argv filtering in SDLMain.cpp since NativeInit no longer
reads argv itself.

Add unittest/TestTextureReplacer which creates a fictive texture pack
(textures.ini with readable invented hashes plus real PNG files), loads
it via the replacer, and verifies lookups, filtering, hashranges, mip
levels, and missing/ignored entries.
To make the replacer runnable outside the emulator:
- The constructor now accepts a null DrawContext (formats just default
to unsupported).
- FindReplacement/FindFiltering use the replaceEnabled_ member instead
of the global config.
- Added TextureReplacer::LoadPackForTesting() to load an ini from a
path directly.
The LZRC decompressor's only bounds check for output (and input) was a
debug-only _dbg_assert_msg_, which is a no-op in release builds. The
NPDRM demo block device also passed a hardcoded 1 MiB output length
while the real destination buffer (blockBuf_) could be as small as 2048
bytes, allowing a crafted NPDRM image to trigger an unbounded heap
overflow during game load.
Changes:
- rc_putbyte/rc_getbyte now enforce real bounds and set an error flag
instead of relying on debug asserts; decompression aborts with -1 on
overflow or truncated input.
- normalize() reads via rc_getbyte so it stays in bounds.
- Plain-text path clamps the copy size to both the output buffer and the
remaining input (and no longer interprets the size as signed).
- NPDRMDemoBlockDevice::ReadBlock passes blockSize_ (the real buffer
size) instead of 0x00100000 to lzrc_decompress.
- Add unittest/TestLzrc (synthetic input, no test data files): checks the
plain-text clamp, truncated input, and output overflow all fail safely.
- AGENTS.md: note to reuse existing format handlers/decompressors before
writing new ones.
A crafted zip with a parent-directory ("..") entry name could escape the
destination directory during extraction, writing arbitrary files on the
host (e.g. into startup/autostart folders). ExtractZipContents built the
output path by concatenating the raw zip entry name onto the destination
with no traversal check.
Changes:
- Add HasParentDirComponent() utility in Core/Util/PathUtil and use it in
GameManager::ExtractZipContents to reject entries with a ".." component.
Guard both the directory-creation and file-writing passes.
- Expose ExtractZipContents as public for testing.
- Add unittest/TestZipSlip which crafts a zip with a "../evil.txt" entry
and verifies it is not written outside the destination directory.
