A dump with sce_sys/playgo-scenario.json and no chunk table lists chunks 0
to 999 through scePlayGoGetChunkId, but every other id was still reported as
installed. Destruction AllStars (PPSA02630) asks for chunk ids from 0 up until
one is rejected; because no id ever was, the walk wrapped the 16-bit id and
grew an array of 16-byte entries until a 5.18 GiB allocation failed about one
second into startup ("Ran out of memory allocating 5565054976 bytes").
An id outside the listed 0 to 999 is now answered like an unlisted id of a
dump without any playgo file: APS5_PLAYGO_UNLISTED_CHUNKS=installed or
=absent answers it, and without an answer the call throws naming the missing
chunk table.

AnyPS5 resolves a title's imports by NID, so a title that imports a system
function no library provides fails to load with an unresolved import. The
PS5 3.20 export inventory lists 193 such exports across 37 PS5 system
libraries AnyPS5 implements but does not provide.
Declare them as throwing stubs so those titles load and reach their next
blocker. Each declaration calls NotImplemented_nid_no_patch and returns 0;
none of them implements the function. Declarations with a credible
prototype use it and cite the source with a pinned commit, and the rest
are declared without parameters, which resolves the import without making
an ABI claim. The technical-debt files record the limitation per library.
libSceMbus and libSceSystemService are left out because pull request #7821
declares them. libSceAgc is left out because its exports are versioned, so
the 3.20 NID names a different symbol from the one AnyPS5 ships.
libSceAvPlayer.native is left out because it compiles libSceAvPlayer's
Export.cpp.
Names and NIDs come from the PS5 3.20 export inventory at

A dump with sce_sys/playgo-scenario.json and no chunk table already answers
every chunk id as installed, but scePlayGoGetChunkId listed only chunk 0.
Ghost of Tsushima (PPSA02225) builds its set of installed chunks from that
list and never reads its English audio, two of its music archives or its
opening movie. scePlayGoGetChunkId now lists ids 0 to 999, the room that
title passes.

A dump is fully installed, so scePlayGoGetSupportedOptionalChunk and
scePlayGoGetOptionalChunk report every optional chunk (language pack) like
scePlayGoGetLanguageMask reports every language. They returned an empty
bitmask, so PPSA01748 hid every text language its playgo-scenario.json
lists as a chunk language, English included.

A package with no playgo-* file in sce_sys has no PlayGo data, so only chunk 0
is valid and any other id returns SCE_PLAYGO_ERROR_BAD_CHUNK_ID. A package with
playgo-scenario.json but no chunk table (PPSA01748) keeps accepting every id.
A chunk table (playgo-chunk.dat or playgo-chunkdefs.xml) still decides when it
exists. A sce_sys that holds other playgo-* files without a chunk table or a
scenario file, or a playgo-chunk.dat that is not a plgx table with a nonzero
count, throws naming the file, since no such dump is known.
Without this a title that walks the ids until the first error (Sifu PPSA03001)
never gets the error.
