Feature/quest persistence

[Truphile]

closes #268

Here is a summary of the changes:

1. Persistence Store ( lib/gamification/quest-store.ts ):
   • Created the store to manage writing and loading the quests , questStats , and agentXp data structures using the provided JSON format.
   • Implemented atomic writes by writing the serialized JSON to .data/quests.json.tmp first, then utilizing fs.renameSync to safely swap it to .data/quests.json .
   • Added a fallback mechanism that initializes the store with empty data and emits a console.warn if the parsed JSON is corrupt.
   • Included an auto-execution hook using a globalThis flag openStellarQuestStoreLoaded which calls loadQuestStore() exactly once upon the first import of the module.
2. State Integration ( lib/gamification/quests.ts & lib/gamification/xp.ts ):
   • Modified hydrateSubTasks in quests.ts to hydrate subtaskDb directly from the stored questStoreData.quests entries on startup.
   • Hooked persistQuestStore() into the addSubTask and updateSubTask functions to automatically capture new state when subtasks are progressed.
   • Modified xp.ts to hydrate agentXpDb on initialization and persist whenever awardXP updates an agent's experience.
3. Unit Tests ( lib/gamification/quest-store.test.ts ):
   • Added a complete Vitest suite to evaluate the persistence logic.
   • The test validates that completing a quest's subtask updates the memory store, correctly serializes the status to string, and successfully restores the "completed" status after deserializing from a simulated restart.
   • Included an additional test case to cover the fallback behavior when the JSON is found to be corrupt.
4. Version Control:
   • The functionality has been staged and committed successfully to the new feature/quest-persistence branch.

Same as PR#325 — conflicts with main. Rebase after PR#322 merges since you share files with it. git rebase upstream/main && git push --force-with-lease

Three TS errors to fix:

1. questStoreData is not exported from ./quest-store — use the existing exported accessor instead, or export it explicitly
2. persistQuestStore doesn't exist — the exported name is resetQuestStore. Rename your function or export it with the correct name
3. Parameter 'q' implicitly has an 'any' type in quest-store.test.ts lines 54 and 72 — add explicit type annotation: (q: QuestRecord)

Also rebase on main first to pull in recent changes to quest-store.ts.
