Complete Emberbound survival adventure and delivery pipeline

[cihat-kose]

Change

Complete the Java adventure prototype as Emberbound, a playable survival game: choose a character, explore three regions, manage equipment and healing, collect supplies, and return home to escape. Add explicit defeat, safe retreat, one-time rewards, and validated save/resume behavior.

Separate game rules from the terminal and persistence adapters. Move to a Java 21 Maven project with executable JAR and launchers, a deterministic full-game demo, Windows/Linux CI, formatting and coverage checks. Add English/Turkish documentation, architecture notes, and portfolio presentation assets.

Validation

• Java 21: mvnw.cmd --offline --batch-mode --no-transfer-progress clean verify — 86 tests, no failures; 300 seeded campaigns across all three characters; 98.25% line coverage.
• Windows: play.cmd --demo completes the real game; packaged --help works.
• Combat, purchases, corrupted saves, failed writes, input recovery, and save/resume are covered by regression tests.
• Gameplay rules match the documentation; relative documentation links and git diff --check pass.
