openkal-musl 0.17.0: register it, and it asks nothing of the floor (#447)

0.17.0 states what the library does NOT supply --- a top-level
`[c-abi-absent]` table of 24 rows, each naming the shape in which that absence
reaches a program, with the package's own CI asserting every row against the
objects it builds. It also moves the implementation pins to openkal-linux
0.15.0 and openkal-windows 0.10.0. No source changed.

`min_mcpp` DOES NOT MOVE, and that is measured rather than assumed. mcpp
ignores a top-level table it does not know and refuses an unknown MEMBER of a
table it does know, so the first spelling of that table made every engine
below 2026.9.20.1 refuse the whole manifest on every target. It is top-level
now, and openkal-musl's own CI builds 0.17.0 green against the published
2026.9.18.3 --- this index's current floor. All 231 descriptors parse with
that same engine, so the descriptor grammar is unchanged too.

The hash was recomputed from a fresh download of the GLOBAL url, and the CN
asset was fetched in full and compared byte for byte against it: equal.

Two other things this touches:

  * The entry lands in all three platform blocks. It went into `linux` alone
    first, and `check_platform_version_parity` caught it --- the omission
    would have read as "0.17.0 not found" on macOS and Windows while the file
    plainly contained it.

  * The descriptor's header note said 0.15.0 was pending and unlisted. It had
    been released and registered, and so had 0.16.0. A note claiming a
    published version does not exist reads as missing data rather than as a
    stale sentence, so it is replaced rather than amended.
