v1.4.5 — compatibility mirror of v1.4.11 (z80cpmw 1.0.17 disk-catalog fix)

Compatibility release — republishes v1.4.11's disk assets under the v1.4.5 tag.

The Windows client z80cpmw 1.0.17 has its disk-catalog URL pinned to the tag v1.4.5, which was never published. As a result, Settings → disk catalog fails with HTTP 404 on every 1.0.17 install (there is no local fallback for the catalog).

This release makes that pinned URL resolve, so already-installed 1.0.17 clients load the disk catalog again with no app update required.

• disks.xml + all disk images are byte-identical to v1.4.11 (catalog schema v13; includes the W8-fixed hd1k_combo.img).
• Marked as a pre-release so it does not replace v1.4.11 as "Latest".

Matches the RomWBW HBIOS v3.5.1 ROM embedded in z80cpmw 1.0.17 exactly as well as v1.4.11 does — every OS-bearing disk image is identical between the two. It does not change the pre-existing HBIOS/CBIOS version-skew notice (tracked separately under the RomWBW v3.6.0 realignment).
