Picasso96 migration, OS4 bug fixes and features

Program bumps to 5.99, library and dopus5.module to 73.3, and commands remain at 65.1.

Picasso96 / RTG display overhaul

• Migrated the RTG subsystem from cybergraphics.library to Picasso96API.library with a CyberGraphX fallback, fixing drag-mask rendering and 24-bit ILBM decoding on modern graphics cards across all platforms.
• Fixed 24-bit ILBM handling: route decisions through colour-plane count, clamp uncompressed chunky decode to width, decode all source planes into the chunky buffer for DIF_WRITEPIX, and prevent 24-bit decode into the 8-bit fallback buffer.
• Hardened drag-mask handling: validate P96 stride before per-row reads, read Memory / BytesPerRow via p96LockBitMap, fix hicolor compare, stop P96 re-entry under lock, and probe RTG via p96GetBitMapAttr.
• OS4: validate interface acquisition for both P96 and CGX, and guard NULL in teardown.
• AROS: compile out P96 call sites and route RTG through CyberGraphX.
• Cleaned up dead P96Base / IP96 globals from all module init files.
• Added full Picasso96 SDK headers: proto, inline, ppcinline, and pragmas.

Covers PR #2 (p96-migration), 26 non-merge commits.

OS4 bug fixes ported from derfsss/dopus5-os4

• Fix filetype editor crash: remove spurious REG(a2) from OS4 proc_init.
• Fix anti-aliased font progressive bolding: use JAM2 draw mode instead of JAM1 so previous weight layers accumulate correctly.
• Fix Escape key not closing requesters on OS4.
• Fix backdrop disappearing on settings save: FUNKOFF was mistyped as FUNK0FF, so the backdrop-off code never compiled in.
• Port defensive lock validation and 255-character filename support.

Covers PR #5 (port/derfsss-os4-bugfixes), 5 commits.

OS4 features ported from derfsss/dopus5-os4

• Raise font requester cap from 30pt to 96pt for 4K / HiDPI displays.
• Add a full-path-in-lister-title option: new LISTEROPTF_FULL_PATH flag shows the complete expanded path instead of volume:objectname.
• Show human-readable free memory on the OS4 screen title bar using BytesToString, for example 324.5 MB free.
• Fix CatCompBlock binary encoding for the two new catalog strings; lengths must include null separator bytes.
• Fix a pre-existing buffer overflow in lister title construction: unbounded strcpy / strcat into the 300-byte title buffer, plus overflow of last_status[80] from the 300-byte title.

Covers PR #6 (port/derfsss-os4-features), 6 commits.

Other fixes

• XADOpus: handle non-Amiga LHA directory entries during extraction. Covers PR #4.
