refactor: derive project root in config.ts from __dirname

Replace the hardcoded `../../package.json` lookup with a
layout-aware project-root resolution that works for both the
source tree (modules/) and the compiled output (dist/modules/).
The new helper detects the `dist/modules/` shape and walks up
one extra level; otherwise it falls back to the parent of
__dirname, which matches the previous behaviour for source.

No behavioural change under the current tsconfig (rootDir: "."
with outDir: "./dist" produces dist/modules/config.js, where
both the old and new expressions resolve to the same path).
The refactor future-proofs the lookup against a `rootDir:
"modules"` change that would otherwise break version reads
from the compiled bundle.
