deploy: static binary and a compose project name that does not collide

Two failures from the first real deploy, both repo-side:

1. The container logged "exec /usr/bin/resume-server: no such file or
   directory" and restarted until the health gate failed. The build host has
   cgo enabled, so the binary carried the nix glibc interpreter, and the
   distroless/static image has no dynamic loader. Every SQLite path already
   uses pure-Go modernc.org/sqlite, so build with CGO_ENABLED=0 and ship a
   static binary.

2. Compose warned about orphan containers ai-resume-backend-1 and
   ai-resume-db-1: /home/sam/deployment/ai-resume on .13 already owns the
   `ai-resume` compose project (on the ai-mesh network). Sharing the name makes
   each stack visible as orphans to the other, so a `compose down
   --remove-orphans` in either could stop the other. Run the site as project
   `ai-resume-site`; the image tag stays ai-resume:local and the port binding,
   mem_limit and memswap_limit are untouched.
