Repair and optimization

Bug Fixes:

• Fixed an issue where the Shattered Star Map wouldn't advance correctly even after a Boss/monster had died; querying, clicking on tiles, and initiating battles will now automatically repair defeated Boss tiles, and battle settlements will advance the map based on the complete annihilation of monsters.

• Fixed an issue with hero selection in the Shattered Star Map, preventing the selection of non-existent or deceased heroes, and now searching for deployable heroes according to a fixed battle position order.

• Fixed the risk of non-distribution or duplicate distribution of leaderboard rewards in merged server events; added an idempotent marker for leaderboard reward distribution.

• Fixed an issue where guild wars would "start but not enter combat"; digitally validated challenge difficulty parameters and verified bot difficulty configurations on the cross-server intermediate server side; invalid parameters will directly return an error.

Optimizations:

• Optimized the defensive lineup determination issue in the Astral Trial, preventing backup or invalid positions from participating in survival/death assessments, and improving the accuracy of stage status, enemy display, and battle settlements.

• Optimized the settlement windows, empty leaderboard handling, and reward logs for the Ice Dragon ranking and achievement rankings.

• Adjusted the threshold for part-time/growth-type activity tasks: Bounty Tasks 150 -> 120, Champions League wins 250 -> 200, Astral Trial wins 100 -> 60, Red Bounties 7 -> 1, Shattered Star Chart Guardians 150 -> 100;

• Adjusted the return policy for selling Talent items: 600 Talent Shards will be returned when selling Talent items;

• Lowered the diamond prices of some shop items: Star Chart Keys from 9999 to 1500, Legendary Equipment Chests from 8888 to 6000;

• Added a new event help announcement explaining the rules for hero acquisition rewards, purchasing advanced rewards, and additional stage completion rewards;
