fix(make-pdf): run setup before preamble footers

[jbetala7]

Fixes #1389.

Summary

• Move the generated MAKE-PDF SETUP block into the make-pdf preamble path so it appears immediately after the runnable preamble.
• Remove the now-redundant template placeholder and regenerate make-pdf/SKILL.md.
• Add a regression test for setup ordering and uniqueness.

Testing

• git diff --check
• bun run gen:skill-docs --dry-run
• bun test test/gen-skill-docs.test.ts --test-name-pattern "make-pdf setup ordering"

Note

• Full test/gen-skill-docs.test.ts still has local external-host freshness failures in this checkout; the tracked Claude-host docs are fresh.
