jolt build: default output under target/{debug,release}, resolved against the project

Browse source 
Build output landed in the CLI's cwd (the jolt repo, since bin/joltc cd's
there), not the project — so a bare -o path or the default binary appeared
in the wrong place. Resolve output against JOLT_PWD, and default it cargo-
style under the project's target/: target/release for release/--opt,
target/debug for --dev, named after the project dir. The <name>.build scratch
dir sits beside the binary, so it lands under the same target dir. -o is
honored — absolute as-is, relative against the project.
