Purely a naming-convention change per user request, not a format
change - the output is still a real ELF shared object (-shared -fPIC),
still dlopen()-able exactly as before. .jtc ("jet compiled") marks it as
an APIServer-loadable content module rather than a generic library.
build-shared.sh: usage text and STEM derivation
(basename "$OUTPUT" .so -> .jtc) both updated - the STEM change is the
one functional piece here, everything else in this commit is comments/
usage strings. Doc comments in jetc.cpp/JetCodegen.h/host_test.cpp/
api_test.cpp updated to match.
Verified live: rebuilt jetc and all five demo*.jtc modules, reran
api_test/host_test against demo3.jtc (still resolves jetc_api_demo3/
jetc_render_demo3 and renders correctly) - the extension is purely
cosmetic to dlopen(), as expected.

# Compiles a .jet file into a shared object (conventionally named .jtc -
|
|
# "jet compiled" - to mark it as an APIServer-loadable content module, not
|
|
# a generic .so) exporting a stable, dlsym()-able render entry point -
|
|
# `jetc_render_<basename>(jet::Global &global, coreutils::MString &out)`
|
|
# - for a long-running server to load and call directly instead of
|
|
# spawning a jet-2.0 process per request.
|
|
#
|
|
# Usage: ./build-shared.sh <input.jet> <output.jtc>
|
|
#
|
|
# The host server links/dlopen()s the .jtc and calls the exported symbol
|
|
# (see the "entry symbol:" line jetc prints) with its own jet::Global -
|
|
# this script does not decide that lifecycle, only builds the module.
|
|
# coreutils::Exception propagates out of the call uncaught; the host
|
|
# decides how to handle a rendering failure (log it, 500, etc.).
