#2781 Price-based emissions with miner-burn scaling (+ locked transfer flags) BREAKING MERGED feature
子网排放模型从基于TAO流改为基于价格，新增root_proportion和miner_burned加权因子，同时引入locked alpha接收标志和拒绝检查
判级：直接修改核心emission分配逻辑（价格加权×root_proportion×miner_burned），新增存储和extrinsic，bump spec_version，影响资金和共识机制
关键改动
  • pallets/subtensor/src/coinbase/subnet_emissions.rs: get_shares从get_shares_flow改为基于EMA价格，再用root_proportion×(1−miner_burned)加权后归一化
  • pallets/subtensor/src/coinbase/run_coinbase.rs: alpha_injection_cap从alpha_emission_i.min(tao_block_emission)改为root_proportion_i×alpha_emission_i；新增MinerBurned存储记录每个tempo的扣押比例
  • pallets/subtensor/src/coinbase/root.rs: dissolve_network中增加MinerBurned::remove清理
  • pallets/subtensor/src/lib.rs: 新增存储AccountFlags(coldkey->u128)和MinerBurned(netuid->U96F32)，定义常量ACCOUNT_FLAGS_ACCEPT_LOCKED_ALPHA
  • pallets/subtensor/src/staking/lock.rs: coldkey_swap和do_transfer_stake中加入目标coldkey拒绝locked alpha检查；coldkey_swap中修复DecayingLock转移顺序（先移除旧lock，转移DecayingLock，再为新coldkey插入lock）
  • pallets/subtensor/src/macros/dispatches.rs: 新增extrinsic set_reject_locked_alpha(call_index 139)
  • pallets/subtensor/src/macros/events.rs: 新增事件RejectLockedAlphaUpdated
  • pallets/subtensor/src/macros/errors.rs: 新增错误AccountRejectsLockedAlpha
  • pallets/subtensor/src/weights.rs: 权重更新（do_transfer_stake增加一次AccountFlags读取）
  • runtime/src/lib.rs: spec_version从419升至421
  • 测试文件大量修改：subnet_emissions.rs完全重写为新模型测试，coinbase.rs移除flow测试改用price，locks.rs新增locked alpha拒绝相关测试，networks.rs验证MinerBurned在dissolve时被清除
