llmapi: add 0.2.8 (project templates)

GLOBAL: GitHub tag tarball (sha256 verified). CN: gitcode mcpp-res
release asset, byte-identical per mirror convention. 0.2.8 ships
templates/ (openai default, chat, anthropic, deepseek) consumed by
`mcpp new <name> --template llmapi` (needs mcpp > 0.0.52 for the
namespaced template fetch fix, mcpp-community/mcpp#130). 0.2.7 is
skipped: its default template did not compile under import std.
