Release v0.10.0

Added

• A prompter_state_index_full_ceiling_usd metric that reports the full-run ceiling recorded for today's index spend (#86)

Changed

• The bot's indexing limits are now $0.25 per run and $0.50 per day, the same as the scheduled index Job. The bot still cannot start a paid full reindex (#86)
• Index spend alerts recognize a confirmed full-reindex day. On that day the usual tiers are silenced, spend above the daily limit raises a warning, and only spend above the recorded full-run ceiling pages as critical (#86)
