Subject: [PATCH 01/16] feat: add platform spec tests, fix syntax issues,
 update CI

- Add tests/platform_check.sp with 34 specs across 13 pure helpers
- Fix clause ordering in File.sp, Dir.sp, Cmd.sp (! before uses)
- Fix main.sp import syntax, examples remove invalid top-level uses
- Add spore-check job to CI workflow

Subject: [PATCH 02/16] ci: remove spore test step until spore-test lands on
 main

The spore test subcommand is in spore-lang/spore PR #55 and not yet
on main. Remove the step to unblock CI; re-add once #55 merges.

- Restore /// doc comments on all platform/*.sp files (spore formatter now preserves them)
- Fix error set syntax: ! [Error] → ! Error (D11: pipes, no brackets)
- Fix clause order: ! before uses (parser requirement)
- Fix hello.sp: remove invalid module-level uses, Unit → ()
- Remove Ruby error-set normalization workaround from CI (no longer needed)
- Fix README: update code example and error set documentation
