fix(pdftract-4iier): correct typo in scientific_paper README and fix xtask path handling

- Fix typo: "scific_paper" -> "scientific_paper" in fixture path
- Fix xtask path resolution: use relative path ".." to access workspace root
- Fix xtask format string: remove unused profile_name placeholder
- Add workspace exclusion to xtask/Cargo.toml for standalone build

These are minor improvements to the existing per-profile README documentation
that was already created in commit 8b5dd4f.
