Subject: [PATCH] feat(01-01): sqlc config, tailwind input CSS, air live-reload
 config

- sqlc.yaml: postgresql engine, schema points at migrations/ (Pitfall 7), pgx/v5 sql_package
- tailwind.input.css: @source globs for templ + internal/web Go files (Pitfall 3), @imports four ui/*.css files per UI-SPEC
- .air.toml: watches .go + .templ, excludes generated *_templ.go (Pitfall 5), runs 'templ generate' pre-build
- Tailwind watch is NOT wired into air pre_cmd (two-terminal workflow per RESEARCH Open Q2)
