book: Spanish edition + step-by-step Quick Start + dedication (release v26.06.111)

[ancongui]

What

Makes PyFly by Example bilingual and more beginner-friendly, and ships it in the v26.06.111 release.

Book — English

• New Quick Start tutorial "Build Lumen Step by Step": from an empty folder to a running, tested wallet feature (open → deposit → read balance over HTTP → test → react to a domain event), as a dedicated front part before Part I.
• Every chapter deepened into a gentler, step-by-step tutorial — numbered Steps, "Run it" checkpoints with expected output, and plain-language glosses on first use of jargon — while preserving all prose, Spring-parity callouts, recaps, exercises, and verified listings.
• Built with an extract → author → adversarial critic → fix workflow; the critic caught 10 HIGH + 8 MEDIUM issues (fabricated APIs, 2 markdown breaks) which were fixed and re-verified against src/pyfly. verify_code: 0 failing listings across 29 files; build green; book tests pass.

Book — Spanish (new)

• Full Spanish edition under book/manuscript-es/ (manifest book.es.yaml), built to pyfly-by-example-es.{epub,pdf}. Translated with a shared terminology glossary (es-ES, informal tú); code, ::: directives, {.recap}/{.exercises} classes, callout keywords, and image paths preserved byte-for-byte. Structural parity vs the English manuscript verified (0 mismatches); ES verify_code clean; ES build green.
• The cover title stays "PyFly by Example" (per request); chapter/part titles and all prose are Spanish.

Dedication (EN + ES)

To Jacinto Arias and the Taidy team — "Because of you there is, at last, one way to do things. One. Single. Way. (We give it a week.)" / "Gracias a vosotros, ahora por fin sí se harán las cosas de una única forma. Una. Sola. Forma. (Le damos una semana.)"

Build system

• book/build/build.py parameterized for multiple languages: --config, per-manifest manuscript_dir / output_basename / localized labels. EN unchanged in behavior.

Framework fix

• pyfly new no longer scaffolds the removed pyfly.web.port key — the project template now emits pyfly.server.port under server: (Spring server.port parity). The legacy key was removed in v26.06.102 and left a dead key in scaffolded apps. No test pinned the template.

Release (v26.06.111)

• Version bumped (__init__.py + pyproject.toml) + CHANGELOG entry.
• release.yml now also attaches the four book artifacts (EN+ES EPUB/PDF) to the GitHub release.
• .gitignore allowlists the ES artifacts under book/dist/.

Notes

The four EPUB/PDF artifacts are committed to book/dist/. Book version strings remain "v26.6.110" intentionally — that is the framework version the listings were verified against, and "new in v26.6.110" statements are historically accurate (111 adds only the book + the scaffold fix, no API change affecting listings).

After merge, tagging v26.06.111 triggers the release.
