### Describe Your Changes
VictoriaLogs allows logs without `_msg` field or `_msg` field is empty.
This lead to incorrect search result. See:
https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6785
This pull request search for non-empty `_msg` field before log entry is
added to `LogRows`.
New counter `vl_rows_dropped_total{reason="msg_not_exist"}` is
introduced.
Example log output:
```
2024-09-23T02:33:19.719Z warn app/vlinsert/insertutils/common_params.go:189 dropping log line without _msg field; [{@timestamp 2024-09-18T13:42:16.600000000Z} {Attributes.array.attribute ["many","values"]} {Attributes.boolean.attribute true} {Attributes.double.attribute 637.704} {Attributes.int.attribute 10} {Attributes.map.attribute.some.map.key some value} {Attributes.string.attribute some string} {Body Example ddddddddddlog record} {Resource.service.name my.service} {Scope.my.scope.attribute some scope attribute} {Scope.name my.library} {Scope.version 1.0.0} {SeverityNumber 10} {SeverityText Information} {SpanId eee19b7ec3c1b174} {TraceFlags 0} {TraceId 5b8efff798038103d269b633813fc60c}]

Previously the original timestamp was used in the copied query, so _time:duration filters
were applied to the original time range: (timestamp-duration ... timestamp]. This resulted
in stopped live tailing, since new logs have timestamps bigger than the original time range.
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7028
This pipe is useful for debugging purposes when the number of processed blocks must be calculated for the given query:
<query> | blocks_count
This helps detecting the root cause of query performance slowdown in cases like https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7070
Previously per-token hashes for per-block bloom filters were re-calculated on every scanned block.
This could be slow when the number of tokens is big or when the number of blocks to scan is big.
Pre-calculate hashes for bloom filters and then use them for searching in bloom filters.
This improves performance by 2.5x for in(...) filters with many values to search inside `in()`.
Previously (f1:foo OR f2:bar) was incorrectly returning `foo` token for `f1` and `bar` token for `f2`.
These tokens were used for checking against bloom filter for every data block, so the data block,
which didn't contain simultaneously `foo` token for `f1` field and `bar` token for `f2` field, was skipped.
This was incorrect, since such a block may contain logs matching the original OR filter.
The fix is to return common tokens from `OR`-delimted filters only if these tokens exist at EVERY such filter
for the given field name. If some `OR`-delimited filter misses the given field name, then `OR`-delimited filters
do not contain common tokens, which could be used for checking against bloom filter.
While at it, add more tests covering various edge cases for filters delimited by AND and OR.
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6554
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/pull/6556
* updates change log
* adds VL-Debug http header
* updates doc
* extracts only the first value of http headers for VL-Stream-Fields and VL-Ignore-Fields.
It makes behaviour the same as Query string args. And allows to easily configure client applications.
Since most of the client collectors don't support multi value headers.

Previously the in-memory buffer could remain unflushed for long periods of time under low ingestion rate.
The ingested logs weren't visible for search during this time.
The set of log fields in the found logs may differ from the set of log fields present in the log stream.
So compare only the log fields in the found logs when searching for the matching log entry in the log stream.
While at it, return _stream field in the delimiter log entry, since this field is used by VictoriaLogs Web UI
for grouping logs by log streams.
### Describe Your Changes
- Fixed the update of the relative time range when `Execute Query` is
clicked
- Optimized server requests: now, if an error occurs in the `/query`
request, the `/hits` request will not be executed.
#6345 (duplicates: #6440, #6312)
The TryParseTimestampRFC3339Nano() must properly parse RFC3339 timestamps with timezone offsets.
While at it, make tryParseTimestampISO8601 function private in order to prevent
from improper usage of this function from outside the lib/logstorage package.
Updates https://github.com/VictoriaMetrics/VictoriaMetrics/issues/6508
- Added a bar chart displaying the number of log entries over a time
range.
#6404
- When `_msg` is empty, all fields are displayed in a single line.
- Added double quotes when copying pairs: `key: "value"`.
- Minor style adjustments.
Add support for markdown format and emoji for the `_msg` field in the
"Group" view.
Add markdown rendering toggle. Disabled by default. Value is stored in
`localStorage`.
This PR fixes an issue where parsing long `_msg` values caused errors,
resulting in some log records not being displayed.
The error occurred due to partial processing of strings. In some cases,
a long record could be split into multiple chunks, causing only part of
the record to be processed instead of the entire entry.
