v1.6.0

PuzzleTea v1.6.0

This release introduces a new game, improves game session lifecycle reliability, expands deterministic seeding controls, and includes a broad performance/test pass across generators.

Highlights

• Added Nurikabe as a full puzzle package with modes, solver, generator, help docs, tests, daily support, and VHS previews.
• Added puzzletea new <game> [mode] --with-seed <seed> for deterministic generation within a chosen game/mode.
• Improved async spawn/session lifecycle handling with cancellation support, stale-job protection, and safer save/status transitions.
• Stabilized cross-game help/status row layout and polished solved-state views.
• Tuned generator/solver paths for Nonogram, Nurikabe, Takuzu, Hitori, Sudoku, Hashiwokakero, Shikaku, Word Search, and Lights Out.
• Added benchmark/invariant/behavior tests across app, UI/theme/stats, and multiple game packages.

Added

• New game: Nurikabe (Mini, Easy, Medium, Hard, Expert) with click/drag input and debug/help integration.
• New app/session helpers for importing saved games, creating records, and running game programs.
• New cancellable spawn interfaces in game/gamer.go:
  • CancellableSpawner
  • CancellableSeededSpawner
• New tests including:
  • app/help_layout_test.go
  • app/spawn_test.go
  • app/update_test.go
  • benchmark/invariant/uniqueness suites in puzzle packages.

Changed

• CLI/docs now distinguish seeding modes:
  • --set-seed for deterministic game/mode/puzzle selection.
  • --with-seed for deterministic puzzle generation in explicit game/mode.
• Daily mode pool now includes Nurikabe and hardened type checks in daily/resolve paths.
• Stats/profile rendering and viewport sizing updated for more consistent layout.
• Category hover bar and themed UI accents now use the shared theme color set.
• Several solved views now hide instructional status text to reduce noise.

Performance & Reliability

• Major generator/solver optimizations across core puzzle packages.
• Better nonogram caching/branching heuristics and bounded cache behavior.
• Improved backtracking heuristics in sudoku/takuzu/hitori/shikaku/hashiwokakero/wordsearch paths.
• More defensive store/query helpers and centralized game-record scanning.

Tooling & Assets

• Updated README and AGENTS guidance for seed flag usage.
• Regenerated VHS tapes/GIFs and added Nurikabe media.
• Extended .gitignore with local plans and Go/lint caches.
