Subject: [PATCH 1/2] Fix arithmetic expression crash in project-install.sh

Script crashed with `set -e` due to post-increment returning exit code 1
when chain_depth was 0. Changed to pre-increment so expression always
returns non-zero value.

Subject: [PATCH 2/2] Fix post-increment exit code issues in bash scripts

Replace post-increment ((var++)) with pre-increment ((++var)) to prevent
script termination when using set -e. In bash, ((expr)) returns exit code 1
when the expression evaluates to 0, which happens with post-increment when
the variable is 0.

This fix ensures all commands are installed correctly instead of only the
first one.
