refactor: extract process and finding types into dedicated crates

Extracts two pristine leaf modules into path-only crates:
- homeboy-process (455 LOC, 20 importers): process spawn/signal/lifecycle
  helpers; depends only on homeboy-error + libc + ctrlc.
- homeboy-finding (381 LOC, 22 importers): structured finding/diagnostic types
  for audit and review output; serde only.

Both re-exported via core/mod.rs so crate::core::{process,finding}::* call
sites are unchanged. Not published to crates.io; still ships as the single
homeboy binary. cargo check --lib passes; both crates' unit tests pass.
