Redesign the interaction mechanic into a recursive chain reaction system
where items can trigger cascading reactions. Keys now open themed chests
which produce items that may trigger further reactions, with chain bonus
rewards for multi-step chains (x2/x3/x4+).
- Add 6 themed chests + mysterious chest + alchemist stone catalyst
- Rewrite InteractionEngine with recursive chain loop (max depth 10)
- Add ConsumeTrigger field to InteractionRule for catalyst support
- Add ChainBonusEvent and enrich InteractionTriggeredEvent with context
- Update rendering to show both reacting items and chain indicators
- Add item descriptions with anticipation hints for chain partners
- Update GDD Section 5 with full chain reaction specification
- Remove ChatPanel/EventLog entirely (UIFeature, GameState, MetaEngine,
SpectreRenderer, Program, ChatPanelTests, meta_chat item/box/strings)
- Retouch Space adventure: expand AlienEncounter with 3 proper endings
(RareBoxStory, AlienTrade, BoxContest with flair secret branch),
expand SpaceExploration with fuel-gated choices and deeper branching
- Add (NOUVEAU/NEW) prefix to adventure action when no adventure completed
- Translate character names via localization keys (character.* in en/fr.json)
- Replace hardcoded "(unavailable)" with localized hint or fallback text
- Fix snapshot path to use CallerFilePath instead of fragile ../ chain
- Add Workstations summary section to item_utility_report.txt
Snapshot now writes to tests/snapshots/ at repo root instead of the test
bin output directory, so it can be committed and diffed across changes.
Crafting entries now show the workstation (e.g. "@ DrawingTable") for both
ingredients and outputs. Removed timestamp from report header to keep
snapshots stable across runs.
