Add sceFontGetVerticalLayout (NID: 3BrWWFU+4ts) to the Font module,
completing the vertical-text counterpart to the existing
GetHorizontalLayout. The SceFontVerticalLayout structure is three
floats (baseline, lineAdvance, decorationExtent) interpreted for
vertical writing such as CJK text rendered top-to-bottom.
- Write baseline=8.0f, lineAdvance=16.0f, decorationExtent=0.0f
- Validate output pointer and return INVALID_ARGUMENT on null
- Return MEMORY_FAULT when guest writes fail
Tests:
- GetVerticalLayout_WritesExactlyThreeFloats with sentinel guard
- GetVerticalLayout_NullBuffer_ReturnsInvalidArgument

Astro Bot asserts and null-writes when a subsystem init call fails, so
each missing import surfaces as a named crash. This stubs the blockers
observed during bring-up: content export init, eight font calls, and
pad tilt correction. sceFontGetHorizontalLayout writes the same
invented geometry as sceFontGetRenderCharGlyphMetrics and the rest
report success. Together with save data memory2 these take the title
to its splash image and font glyph rendering path.
