hello2 — stdio vs conio output API comparison (fast/no-attr vs
slower/attributed), also exercises textcolor/textbackground.
simple — packed 2-bit style array bit-twiddling smoke test.
banktest — __banked function calls across two explicit banks in huge
memory mode.
hello2.c updated to call the renamed gettextmode/settextmode (see the
conio rename in 5e5e70d).

palette.h/video/palette.c wrap BIOS $A4 PIC_SET_PAL/PIC_GET_PAL and $A6
SET_PAL_INIT for the 8 palette pages (0-3 graphics, 4-7 text planes).
gfx_palette.c and conio/text_palette.c are thin per-domain wrappers;
text_palette.c maps the text "plane" 0..3 (paper/ink/blink-paper/
blink-ink) onto BIOS pages 4..7. Covered by tests/text_palette.

_get_cursor/_set_cursor now use BIOS GetCursor/SetCursor (RST 8, 08Eh/084h)
instead of ESTEX CURSOR/LOCATE; cursor position packed into a two_bytes
union. get_videotextmode/set_videotextmode renamed to gettextmode/settextmode.

Direct __naked z80 wrappers over BIOS LP_PRINT_*/LP_SET_PLACE/LP_GET_PLACE
(RST 8, opcodes 081h-08Eh) for fast text rendering — a single BIOS call
replaces a wrchar() loop for constant-attribute/constant-character runs.
Covered by tests/bios_text.

- Split tests/ (libc feature tests) and examples/ (real apps); shared
app.mk in repo root, was examples/example.mk
- libc/io/* split into libc/{conio,env,errno,file,mouse,string,sys,
time,video}/ — clearer module boundaries
- New examples/mdview/: markdown viewer (Phases 1-5 + light nested
lists). Headers (H1-H4), HR, ulist/olist/quote with nesting via
leading spaces, fenced code blocks, inline emphasis (bold/italic/
underscore/code), wrap/unwrap mode with soft wrap (F2), horizontal
pan (← →) with '>' truncation indicator
- libc additions: scroll() in conio (ESTEX SCROLL), strlwr/strupr,
gets() test
- Makefile updates across tests/ for the new shared app.mk path
