build: strip Jolt debug symbols from Release (55MB -> 11.3MB exe)

Browse Source 
Jolt's GENERATE_DEBUG_SYMBOLS option defaults to ON and injects -g in
every config, so the Release binary carried ~44MB of DWARF sections
(.debug_info/.debug_line/...) from Jolt TUs alone -- 80% of the 55MB
exe. Force the option OFF for Release builds only (the vendored
submodule is untouched; Debug/RelWithDebInfo keep symbols).

Measured: 55.0MB -> 11.3MB, .text unchanged at 8.5MB, zero debug
sections left. The remaining ~1.6MB is the ELF symtab, useful for
crash stacks; plain strip takes it to 9.7MB if a distributable is
needed.
