Problem

Since #609, running a program that imports modules under the JIT (with the JIT cache) fails:

tslang: error: failed to add '...\core\input_pass.ts' to the JIT engine, error: In ...\core\__jit\input_pass.ts.<hash>.obj, duplicate definition of symbol '__tsborrow_compute_nbody_12767637287532266077'

The JIT cache compiles each imported module through runMLIRPasses with isJit off (jitcache.cpp), so BorrowFactsExportPass runs for every import. But the symbol name came from inputFilename, which is always the main program. So every cached import defined the same __tsborrow_<main>_<hash>.

Fix

transform.cpp now builds the name from the module's main source buffer, which is the file actually being compiled. Stdin (-) still uses inputFilename. moduleSymbolSuffix canonicalizes the path, so a normal --emit=obj build gives the same symbol as before.

Also: the modules the JIT cache compiles (isJit off, jitCache on) no longer export facts at all. Their objects are only loaded into the JIT, never linked, and the program run there drops imported facts (StackPromotionPass.cpp:58-63), so nothing ever read them.

Verified

• native_ts_graphics examples/compute_nbody.ts -- -test under the JIT: Test PASSED. Before the fix it failed with the error above.
• The new JIT cache objects carry no __tsborrow_ symbol. With the first commit alone, each had its own (__tsborrow_donut_…, __tsborrow_input_pass_…, …).
• The 92 borrow-facts / stack-promotion / borrow tests pass locally (Windows), including test-borrow-facts-defaultlib.
• --emit=obj core/args.ts, old vs new compiler: same __tsborrow_args_11047768023027654085 and identical facts (--print-borrow-facts).

Caches already written by pre-alpha105 hold the bad objects. A new compiler build gets a new compiler id, so it recompiles them.
