Decode page/offset from the 32-bit offset's bytes to avoid SDCC z80
32-bit shift/mask helpers on the hot path; map_page() uses a cached
file_phys[] table to skip mem_get_page() on every W3 swap.
Behaviour-preserving.

- Add fenced code block tracking to the wrap-pass in index_lines().
line_style is reset to PLAIN at every ``` delimiter, and all segs
inside a fenced block get init_style=PLAIN. This prevents emphasis
markers (e.g. _ in __var) inside code blocks from leaking into later
normal text.
- Also carry init_style across wrap continuation segs so that a long
bold/italic line that is wrapped continues with the correct style on
the next segment.
- The fence bitmap pass now only updates in_code[], since init_style is
already set correctly by the wrap pass.
- 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
