fix(log-watcher): portable wo.toml — no pinned runtime path

Browse source 
The manifest pinned `[build] runtime = "../../../runtime/wovm"`, a repo-only
relative path that overrides woc's runtime resolution — so `woc <copied-dir>`
failed off-repo (e.g. an installed toolchain on a test server) with "runtime
binary not found".

- Drop the [build] section: the project no longer hardcodes a machine path, so
  an installed `woc` self-locates `wovm` beside its own binary.
- The module justfile's `build` recipe now sets WO_RUNTIME=<repo>/runtime/wovm
  so the in-repo build still uses the freshly built VM.
- Acceptance is unaffected (it compiles via `woc --emit` + an explicit $WOVM,
  never the manifest [build] key).

Verified: just log-watcher::build OK; just log-watcher 7/0; and building a
copied tree with the installed-layout woc from an unrelated cwd self-locates
the sibling wovm and produces a runnable binary.
