Driver::RegisterShader required the Shader header at an 8-byte
boundary (alignof(Shader)) and read its fields through the pointer.
PPSA26344 uses its shader packs in place: its compute shader objects
point at headers 4 and 1 bytes past an 8-byte boundary, so the first
sceAgcCreateShader of such a header threw "null or misaligned address".
The header is now checked for null and readable memory at any
address, and its fixed fields and the registers the trace prints are
copied out with memcpy. The code address must still be 256-byte
aligned, and the header and size checks are unchanged. The console's
rule is unknown and is listed in TechnicalDebt.
The end-of-shader action is written by an inline SDK builder as a
RELEASE_MEM packet, so the size is the 32 bytes that
sceAgcCbReleaseMem writes and that sceAgcAcbQueueEndOfShaderActionGetSize
already returns.

20 of the 31 NIDs have names in shadPS4's aerolib list. They are declared
under those names; POSIX sleep is implemented. The NpPartner001 and Psml
MFSR2 exports stay unnamed.

RackGetInfo reports the rack's handles, buffer, id, uid, option limits,
render count and active voices. VoiceGetPortInfo reports a port's matrix,
volume and destination. VoiceQueryInfo answers info id 0x4001 with the
voice channel count and throws for other ids. Assumptions are recorded in
TechnicalDebt.

sceLoginDialogGetResult zeroed 8 bytes of a result struct of unknown size and reported result 0
with user id 0. It now writes only the leading int32 (USER_CANCELED), like
sceWebBrowserDialogGetResult and like the sign-in dialog, so a title takes its "no user chosen"
path instead of reading an invalid user id. Records the dialog in the silent-stubs list in
docs/dev/TechnicalDebt.md.
Per review: sceUserServiceGetNpAccountId reports success with account id 0 and
sceUserServiceGetUserColor returns blue by default; both are assumptions. Records them under
"Unknown function info" in docs/dev/TechnicalDebt.md.
* 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.
