Zig 0.16 removed `Compile.linkLibC()`; libc is now a module property, so set `.link_libc = true` on the `plotille-c` module instead of calling it on the static and shared library artifacts. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Zig 0.16 removed `std.io`. Replace `std.io.fixedBufferStream` with `std.Io.Writer.fixed` and `std.fmt.format(w, ...)` with `w.print(...)`; `getWritten`/`pos`/`reset` become `buffered()`/`end`. `ArrayList` lost its default field values and its `writer()` helper, so initialise with `.empty` and print via `list.print(gpa, ...)`. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Zig 0.16 removed `std.posix.isatty` and the global env-var helpers, so `TermInfo.detect` can no longer reach stdout or the environment on its own. BREAKING CHANGE: `TermInfo.detect(allocator)` becomes `TermInfo.detect(io, environ, allocator)`. Callers pass `init.io` and `init.minimal.environ` from `std.process.Init`.

Write into a `std.Io.Writer.fixed` buffer instead of a fixed buffer stream, and swap the removed `GeneralPurposeAllocator` for the c allocator. `get_terminfo` has no `std.process.Init` to draw from, so it uses the hardcoded single-threaded `Io` and reads the environment block from libc. The exported C signatures are unchanged. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Zig 0.16 hands I/O, the arena, args and the environment to `main` via `std.process.Init`, replacing `argsAlloc` and the hand-rolled arena. stdout becomes a buffered `Io.File.Writer` that is flushed on exit, and stdin is read through `readerStreaming` + `allocRemaining`. In lookup.zig, drop the per-call throwaway stdout writers and reuse the single writer; with buffering they would interleave incorrectly.

Highlights
Breaking change
std. posix.isatty and the global env-var helpers were removed, so terminal detection needs I/0 and the environment passed in:
The exported C API signatures are unchanged -
get_terminfosources both internally.
