- 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
