Youss 3ebfc56d4c [PlayGo] Derive the installed chunk set from the pak files on disk (#438)
A title that ships no PlayGo sidecar was reported as a single-chunk
package. That is wrong for any package whose content is split across
chunks: the title is told everything past chunk 0 is not installed, even
though a locally dumped title has all of its data present.

The Invincible (PPSA06426) ships pakchunk0..8 and asks PlayGo which of
those are available. Receiving BAD_CHUNK_ID for chunks 1..8, it re-queried
scePlayGoGetLocus for the same chunk in a tight loop that never terminated
(observed ~1000 consecutive dispatches with identical arguments).

Discover the chunk ids from the pakchunk<N>-<platform>.pak files present
under the app0 root instead. Those N are exactly the chunks the package
has, so the answer is derived from the install rather than assumed. Chunk 0
is always included, so a title with no pak files at all keeps the previous
single-chunk behaviour, and ids outside the discovered set still return
BAD_CHUNK_ID so title-side chunk enumeration still terminates.

Verified on The Invincible: the discovered set is [0..8], matching the nine
pak files, and the GetLocus retry loop no longer occurs. No regression on
Dead Cells (PPSA15552): still reaches AGC rendering and presents frames.
The existing metadata-free contract test still passes -- its app0 fixture
has no pak files, so the discovered set stays [0].
