fix(billing): 修复时间规则区间恒真表达式导致倍率全天生效 - #6934
Conversation
Overnight range (MATCH_RANGE) unconditionally emitted hour(tz) >= start || hour(tz) < end. For a within-day range like 9-12 (start < end) the || form is a tautology that always applies the multiplier, so the discount/multiplier silently applied 24/7. Emit && for start <= end (within-day range) and keep || only for start > end (overnight range crossing midnight). Also teach the request-rule parser to round-trip the && form back to a single MATCH_RANGE condition. Fixes QuantumNous#6923.
Time rule bounds outside each time function's domain (hour 0-23, minute 0-59, weekday 0-6, month 1-12, day 1-31) could still yield always-true conditions such as hour >= -1 || hour < -5 that silently apply the multiplier 24/7. Drop the whole rule when any bound is out of domain or not an integer, instead of emitting a degenerate expression.

range” i18n key to a neutral “Time range” key, and add corresponding
translations in every supported locale while preserving the existing translation
structure and naming conventions.
- Around line 489-493: Update the condition parsing flow around
tryParseTimeCondition and buildRuleGroupFactor to detect adjacent matching
hour/time lower and upper bounds within a larger top-level conjunction before
splitting other conditions. Combine those bounds into a single MATCH_RANGE
condition, then parse the remaining conjunctions normally, preserving unrelated
conditions such as header comparisons.

Use a neutral label for MATCH_RANGE.
These lines make MATCH_RANGE valid for same-day and overnight ranges. The option still uses the label key Overnight range at Line 649. Users configuring 9-12 see an incorrect mode name.
Replace the key with a neutral i18n key such as Time range, and add its translations. As per coding guidelines, “i18n 键应层级清晰、语义明确且命名一致”.

Source: Coding guidelines
When a time range shares a rule group with other conditions (e.g. param == "x" && hour >= 9 && hour < 12), the parser split the range into two scalar conditions and lost MATCH_RANGE, so reopening the visual editor showed two rows instead of one range row. Merge adjacent matching time bounds (fn >= X && fn < Y) into a single MATCH_RANGE before parsing the remaining top-level conjunctions.

The range regexes and

修复 #6923：修复时间计费规则中，非跨日区间被生成恒真表达式，导致倍率全天生效的问题。
改动 1：按区间方向生成正确的连接符（e1e532a1）
buildTimeConditionExpr对MATCH_RANGE原先无条件生成hour(tz) >= start || hour(tz) < end。当start < end（如 9-12、14-18）时，该表达式对任意小时恒真，规则倍率 24 小时全部生效。修复：自动判别区间方向
start > end（真正跨日，如 21点-6点）保留||，行为不变；start <= end（当日区间，如 9点-12点）改用&&，仅在 9-11 点生效；改动 2：time 规则值域校验（94fcf1df）
start/end 及 EQ/GTE/LT 的 value 增加对应 timeFunc 值域校验（hour 0-23 / minute 0-59 / weekday 0-6 / month 1-12 / day 1-31，且须为整数）。越界值（如
-1 ~ -5、hour >= -1、hour < 24）此前仍会产生恒真表达式，现在直接丢弃该规则，变为倍率恒 1。目前的缺陷 1：规则提示不清晰
同一"跨日范围"模式下，区间方向即语义：
start < end是当日区间（&&），start > end是跨日区间（||）。该规则此前完全不透明，且模式名"跨日范围"与 9-12 这类当日区间字面不符，是用户误配的原因之一。本次按照最小修复原则，未改 UI 文案；后续将模式文案改为中性"时间范围"或在 UI 增加方向提示可能更好。目前的缺陷 2：语义缺陷
buildRuleGroupFactor对无效条件使用.filter(Boolean)过滤。多条件组中若含"恒假型"越界 time 条件（如param=="y" && hour>=25）：修复前整组恒假（倍率恒为1），修复后该 time 子句被删除，组变为剩余条件生效，可能开始计费。单条件组不受影响。该场景触发面极小，需要多条件组 + 无效 time 值，为保留"半填写"容错未改为整组丢弃；如维护者认为应严格化，可改为"组内任一条件无效则整组丢弃"。🚀 变更类型 / Type of change
