build(channels): correct wordlist path for tool-side build invocations

shared/build-lib.sh is sourced from each tool's build.sh with
root_dir pointing at the tool directory, so paths to other shared/
artifacts have to be \$root_dir/../shared/<file>. The slug helper
incorrectly used \$root_dir/shared/build-words.txt, which only
resolves correctly when the helper is invoked from the repo root
(e.g. via the smoke test `root_dir=\$PWD sh -c …`). In a real
./build run, the helper found the wordlist missing and silently
fell back to the short-SHA — the previous beta cut shipped
"v0.0.17-beta · 2026-05-07 · 1dafc97" instead of the intended
slug.

Fix: align the path with the existing shared/favicon.svg pattern.
