* feat(libkernel): implement sceKernelReleaseFlexibleMemory
Unmaps the range through sceKernelMunmap, which returns its pages to
the flexible memory budget, as fpPS4 and prosper do.

* test(libkernel): keep the flexible memory release check apart from the batch map checks

sceAgcCbCondWrite writes the 9-dword COND_WRITE packet: poll a memory
dword, compare it masked with the reference, and write a dword to memory
on a match. sceAgcCbCondWriteGetSize returns its 36 bytes.

sceAgcAsyncCondExecPatchSetCommandAddress and
sceAgcAsyncCondExecPatchSetEnd patch the COND_EXEC packet like their
graphics counterparts, since sceAgcAcbCondExec writes the same packet
as sceAgcDcbCondExec. Both variants share one implementation, as the
REWIND patches do.

The query writes the maximum resource name length (0xfc) through its
output pointer and returns 0, as prosper does from a title's registration
configuration. The parameter follows the SDK wrapper
sce::Agc::ResourceRegistration::getMaxNameLength(unsigned int*). Resource
registration itself stays unavailable.

Rack 0x2001 is created with its option layout and KytyPS5's defaults, takes
the setup (0x20010000) and I3DL2 (0x20010001) voice params and reports the
common voice state. The voice mixes its inputs and runs a Freeverb-style
approximation driven by the I3DL2 parameters: room and room HF, early
reflections and their delay, late reverb and its pre-delay, decay time and
HF ratio, and diffusion. Out-of-range params throw, param changes keep the
tail, a stop or kill clears it, and the tail ends once it decays below
1e-20. The console's algorithm is unknown; the approximation is recorded in
TechnicalDebt. The test context buffer pool grows to 64.

Mastering voice param 0x30000004 sets a full-band and an LFE level. They
scale the mastering voice when it is mixed into the render buffer, the LFE
level on channel 3 of 6- and 8-channel voices. Non-finite levels are
invalid arguments.

The SDK 9 libc.prx heap maps its arenas with flag 0x8000, which threw as
an unsupported flag. The flag is ignored for this function, as sharpemu
does; other unknown flags still throw.

Whether the console's parser rejects 1e309 or stores an infinite real
is unknown, and RFC 8259 allows both. Following the exact-or-throw rule,
sce::Json::Parser::parse now throws with the number text and a note that
the behaviour is unverified, instead of returning JsonErrorParse. The
partially built tree is freed before the exception leaves the parser.
The case is listed under unknown function info in TechnicalDebt.md.

sceAgcWriteDataPatchSetDst, sceAgcWriteDataPatchSetCachePolicy, their
Async forms and sceAgcAsyncWriteDataPatchSetAddressOrOffset threw. They
now rewrite a WRITE_DATA packet in place: the destination in the
graphics (sceAgcDcbWriteData) or compute (sceAgcAcbWriteData) encoding,
the cache policy in bits 25-26 and the address in dwords 2-3, so the
patched packet equals the one written with those values. A register
destination is rejected when the packet requests write confirmation,
as when the packet is written.

PPSA14632 (Unreal Engine) writes sceAgcCbBranch(mode 1, compare
function 0, mask 0, reference 0) with a then buffer and a null else
buffer of 0 dwords. It leaves the compare address uninitialised, so it
is sometimes only 4-byte aligned. The writer rejected the null else
buffer and the misaligned compare address, and the driver accepted
opcode 0x3f only as the 4-dword INDIRECT_BUFFER, so the 14-dword branch
would have failed at submission.
sceAgcCbBranch no longer checks the compare address of an always-pass
branch, which reads nothing, or the address of a buffer of 0 dwords.
The driver runs the first buffer of an always-pass COND_INDIRECT_BUFFER
in modes 1 and 2 (if-then and if-then-else) in place of the packet. A
comparison, a predicated branch and other modes throw.

The 106-key (Japanese) arrangement threw. Its alphanumeric layer now
follows the JIS layout of the HID usages: the symbol keys right of the
digits and letters, the Ro key (0x87) and the Yen key (0x89). With the
Kana LED set it still throws, as the kana the console returns are
unknown.

sceAjmBatchJobControl threw. It now appends a control job that keeps
the sideband input pointer and runs at sceAjmBatchStart: RESET (bit 13)
clears the context as sceAjmBatchJobClearContext does, INITIALIZE
(bit 14) initializes the codec, and SIDEBAND_GAPLESS_DECODE (bit 45)
overwrites the gapless total and skip counts, in this order.
The sideband input holds the gapless decode first, then the codec's
initialize parameters: 8 bytes for ATRAC9, 12 for Opus, none for MP3.
The output is the 8-byte result. Other flags, INITIALIZE for other
codecs, and other sizes throw. SIDEBAND_GAPLESS_DECODE without RESET
throws too: RPCSX and shadPS4 keep zero counts there. The bits and the
order follow shadPS4 (PS4), the overwrite with RESET follows RPCSX, and
the sizes follow the one title seen.
PPSA14632 calls sceAudioOut2Set3DLatency(0xFF, 1) during its audio
setup (eboot 0x5613e2c) and fails the setup on a nonzero return. Only
latency 2 from PPSA26344 was accepted, so the call threw. Latency 1 and
2 are now accepted for the system user; 0, 3 and other users still
throw.

scePlayerInvitationDialogGetResult makes the common dialog checks of
sceWebBrowserDialogGetResult: NOT_INITIALIZED before the dialog is
initialized, ARG_NULL for a null result and NOT_FINISHED until the
dialog finishes. The dialog shows no UI and sends no invitation, so the
finished dialog reports USER_CANCELED with error code 0. The 40-byte
result layout (error code, result, 32 reserved bytes) is taken from
SharpProspero.
