D145 - An exclusion entry with no / names a whole section, because a loader can fail a layer rather than a check

The exclusion list held check ids and nothing else, and the fpPS4 sweep showed what that costs. It found 035-libc/strchr hung, then snprintf, then qsort, bsearch, numeric, strtoul-bases - twenty consecutive checks in one section, each costing two runs to establish, ending in a report whose libc section is twenty separate skips.

Twenty skips invite a reader to look for twenty causes. There is one: this loader does not return from libSceLibcInternal. One entry says that, and says it more accurately than the list of checks that happened to be reached before the round budget ran out.

EXCLUDE="035-libc" now matches any id beginning with 035-libc/. The slash is required rather than a bare prefix test, so a section name cannot swallow a longer one that starts the same way.

It is a claim, so it is not made automatically. The obvious next step - have sweep.sh collapse to a section after N consecutive exclusions in it - is deliberately not taken. The skip reason reads "known to end the process on this platform", and for a section entry that asserts it of every check in the section, including any the sweep never reached. Against fpPS4 that would be a claim about ten 035-libc checks nothing has run.

017-posix is the case that proves the caution warranted: exactly five of its checks hang and the sweep walked past the rest into the next section, so collapsing it would have reported working checks as fatal. A section entry is right when a section fails and wrong when part of one does, and only the completed walk tells them apart.
