Set TERM_PROGRAM and TERM_PROGRAM_VERSION environment variables.

Browse Source 
WezTerm claims this is an emerging de-facto standard for terminal emulator identification:
a103b6d97a/config/src/config.rs (L1526-L1529)

One example of usage in the wild is neovim doing capability detection:
f050aaabbb/src/nvim/tui/tui.c (L206-L211)

Ghostty now reports this:

$echo $TERM_PROGRAM
ghostty

$echo $TERM_PROGRAM_VERSION
0.1.0-main+aa08f3c

I think it's really nice that the commit hash is included, as users can provide this in issue reports. WezTerm does the same.

I use these variables in my tui library in addition to $TERM and $COLORTERM for capability detection, which is what motivated this PR.
