fix(swf): move manifest next to its loader so Railway ships it (#3344)

PR #3336 fixed the yaml dep but the next Railway tick crashed with
`ENOENT: no such file or directory, open '/docs/methodology/swf-classification-manifest.yaml'`.

Root cause: the loader at scripts/shared/swf-manifest-loader.mjs
resolved `../../docs/methodology/swf-classification-manifest.yaml`,
which works in a full repo checkout but lands at `/docs/...` (outside
`/app`) in the Railway recovery-bundle container. That service has
rootDirectory=scripts/ in the dashboard, so NIXPACKS only copies
`scripts/` into the image — `docs/` is never shipped.

Fix: move the YAML to scripts/shared/swf-classification-manifest.yaml,
alongside its loader. MANIFEST_PATH becomes `./swf-classification-manifest.yaml`
so the file is always adjacent to the code that reads it, regardless
of rootDirectory.

Tests: 53/53 SWF tests still pass; biome clean on changed files.
