psx_host_set_input_sink: an overlay provider sees host SDL events first,
in the event drain and the host pause loop, and may consume them.
psx_host_set_ui_capture: while on, local game input reads released and
centred (netplay included, so peers receive "nothing pressed") and the
external-input gate stays closed. Debug builds gain host_key, which pushes
a real SDL key event for scripted runs. Inert without a provider.

A digital presentation folds the sticks onto the D-pad and centres them,
so a transform on a digital player (the default for many titles) never
saw the stick. The transform decides what the guest sees, so for a
digital stage-1 pad with no controller source its frame is now the host
pad: real sticks and buttons without the stick->D-pad fold, type still
DIGITAL (new PadExtHooks.host_pad, capture_pad_slot_view). The output is
pre-filled with the stock pad and a decline delivers it, so pass-through
stays the stock folded digital bytes (mod_pad_transform_run takes the
stock pad). Analog pads, sources and guarded frames are unchanged.
Tests: pad_external_input_test (digital player: frame has the real lx and
unfolded buttons, decline and pass-through deliver the stock digital
bytes, no host-pad query for analog / guarded / source ports),
mod_pad_transform_test (decline returns the stock pad, output pre-filled
from it).

psx_mod_set_pad_transform(player, &PSXModPadTransform) registers stage 2b
of pad_external_input: after the physical pad and any controller source,
before the mouse policy. The transform sees the resolved pad plus the
port's host extras (gamepad present, LT/RT 0..255 from SDL, unthresholded)
and may rewrite buttons, sticks and the presented controller type, e.g. a
NeGcon whose I/II come from the triggers. Output is pre-filled as a
pass-through, validated (struct size, ranges, type within allowed_types)
and replaced by neutral when invalid; detaching or a mod/session reset
owes one neutral release frame. initial_type sets the boot/hotplug type.
The resolver stays pure: host extras arrive through a new capture hook and
the transform through another, both covered in pad_external_input_test.
Under the input guard the transform runs on zero triggers and its output
is neutralized. A NeGcon result resets the mouse policy rather than letting
it overwrite the I/II bytes. Offline only: netplay, resim, selfcheck replay
and plain debug overrides never reach it.
With no transform registered every pad is bit-identical to before.

Mouse policy now folds onto the resolved pad (source included) instead of a discarded capture; no-policy path does no mouse polling.
