What and why

This is split out of #957, as offered in its closing comment. Fire Emblem Fortune's Weave's dump holds updates/131072/ alone, and that update is the whole game. The NSP script had two problems with it: it took base/ as the mark of a dump, and it refused a dump with no profile instead of surveying it.

• pack_dump.py: takes a dump with base/ or with updates/<version>/ folders that hold code and a RomFS. It reads the title ID from the base game, or else from the newest update. It refuses version 0 without base/, and lists the versions there.
• The script: lists v0 only when there is a base, and looks up the build by the newest version's main. A dump with no profile is surveyed from its own files: the code modules are copied, the RomFS is read in place instead of from the manifest, and the folder's name names the game, since a dump has no control data.
• The provisional profile (profile_guess.py) had two errors for a Switch 2 game:
  • The SDK version pattern didn't take a variant (nnSdk-Generic_22_2_0), so the survey showed no SDK.
  • The pool was a Switch 1 one. An sdk built for the Switch 2 (Ounce) now gets a 9 GB pool and a heap region that holds it, as Donkey Kong Bananza's profile has.

Checked

• Tests, with Python 3.14 (the script needs 3.12 or newer, and test_nsp_dump.py fails on main too with 3.9):
  • dm/tools/tests/test_nsp_dump.py: a dump with only an update, and a dump with no profile surveyed until its 32-bit NPDM stops it.
  • test_profile_guess.py: the pool and the variant.
  • test_nsp_scan.py, test_nsp_romfs.py, test_docs.py.
• Games: on this branch, the script found Fire Emblem Fortune's Weave's (04007EF01F8AE000) update-only dump, packed v131072 from the update alone, and built all 16,888 shaders, the host and the pipeline prebuild. Before the rebase, it also surveyed the dump with no profile and wrote the provisional one.
• Devices and OS: MacBook Pro M3 Pro, macOS 27.0.1.
• regress.py: not run. This changes packing, not the host or the chain.
