v2.21.4-alpha1

What's Changed

Fix counter past-time queries returning no data for today's writes
(#4).

Bug Fixes

1. Reader/writer index staleness for realtime counter

CounterWR and CounterRD hold separate MemHashBlock instances on
the same .hfile. The reader loaded the index once when first opening
the day and never saw subsequent writes by the writer. Mirror the
existing daily-counter Reload() pattern for RealtimeCounterData
with a 4s reload interval (matches the writer's flush cadence).

2. Epoch-millis vs seconds-of-day mismatch in counter read handlers

The Java client and Eclipse UI use epoch milliseconds throughout for
stime / etime / time fields, while RealtimeCounterData keys
entries by seconds-since-midnight (0..86399). Handlers passed
int32(stime/1000) (epoch seconds) into ReadRealtimeRange, so keys
never matched. Even if matches existed, the returned timeSec was
emitted as-is, falling outside the chart's [stime_ms, etime_ms]
X-axis range.

Add toSecOfDayRange() helper and apply consistent epoch-millis
conversion to COUNTER_PAST_TIME, COUNTER_PAST_TIME_ALL,
COUNTER_PAST_TIME_TOT, and COUNTER_PAST_TIME_GROUP. Also switch
the first two to GetLong (GetInt truncated the upper 32 bits of
millis to garbage).

Symptom Resolved

Group → Elapse Time → Load → Time All (and other counter past-time
views) now correctly displays both past and newly generated data for
today's date.

Documentation

Two rules added to CLAUDE.md:

• Time semantics on the wire: always epoch milliseconds
• Reader/writer index staleness for today's data
