Yucong Sun 592dfc0688 Prefer .lpc source extension; rename testsuite to .lpc
Source resolution is now explicit-extension-exact: load_object("/foo.c")
probes only foo.c, never foo.lpc (and vice versa); extension-less names
prefer .lpc and fall back to .c. Object identity stays extension-blind:
object names carry no extension, any spelling finds a loaded object, and
the registry is consulted before the filesystem. The caller's raw
spelling now flows through find_object()/inherit/master/simul_efun loads
instead of being pre-stripped away.

- filename_to_obname and otable basename() strip .lpc too (children())
- save_object() strips either source extension before appending .o
- replace_program()/function_exists() handle both suffixes
- testsuite: all LPC sources renamed to .lpc; runner globs, master
  get_include_path cases, and program-name assertions updated;
  README.md rewritten with the extension rules and suite conventions
- new single/tests/efuns/dual_extension.lpc pins exact-pick, fallback,
  no-crossover, identity, and registry-before-filesystem with .c/.lpc
  fixture pairs in /clone

Verified: ctest 297/297 and driver-autotest x3 (ASan Debug) plus
RelWithDebInfo ctest + autotest.
