Default dev builds now emit line-tables-only debuginfo instead of the implicit full DWARF (debug=2). This preserves panic/backtrace file:line, tracing call-site locations, and profiler/coverage symbols, while dropping the variable/type DWARF that dominates codegen time, linker memory, and target/debug disk. Debugger variable inspection (breakpoints/stepping still work) is restored on demand via the new dev-debug profile (cargo build --profile dev-debug -p <crate>) or CARGO_PROFILE_DEV_DEBUG=2.
