Subject: [PATCH 1/2] fix(cli): use ASCII box-drawing characters on Windows to
 fix misaligned help output
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

The help command in metacallcli renders a bordered table using Unicode
box-drawing characters (┌ ─ ┐ │ └ ┘). On Windows the default console
code page (CP850/CP1252) cannot render those code points, causing
every border character to either display as a question mark or take up
a different column width, making the entire help output unreadable.

Introduce CLI_BOX_* macros that select ASCII equivalents (+, -, |) on
Windows (any of _WIN32, _WIN64, WIN32, WIN64) and keep the original
Unicode characters on all other platforms. Replace all hardcoded
border strings in the help() function with these macros.

No behaviour change on Linux or macOS.

Fixes #537

Subject: [PATCH 2/2] fix(cli): enable UTF-8 console output on Windows for
 Unicode box borders
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Instead of falling back to ASCII box-drawing characters, call
SetConsoleOutputCP(CP_UTF8) at the start of help() to switch the
Windows console to code page 65001, then restore the original CP
when done. This lets the same Unicode box characters (┌ ─ ┐ │ └ ┘)
render correctly on both Windows and non-Windows without maintaining
two separate sets of macros.

windows.h is included only under the _WIN32/_WIN64/WIN32/WIN64 guards
so there is no impact on Linux or macOS builds.

Addresses review feedback on #677.
