fix(azure): drop redundant CD log timestamp - #2244
Conversation
CD job log lines already carry the pulumi engine's own timestamp (e.g. "2026-04-28T23:43:03.965786510Z - worker deleting (0s)"), but QueryLogs forwarded that line verbatim as Message while separately stamping Timestamp with time.Now(), so `defang tail` showed two near-identical timestamps per line. Parse the leading timestamp out of the line and use it as the entry's Timestamp, stripping it from Message. Falls back to the old behavior when a line doesn't start with a parseable timestamp. Fixes #2079

- Line 958: Update the non-follow log handling around parseCDLogLine so
multi-line ReadJobLogs snapshots are split into separate cdLogEntry values
before parsing; preserve each line’s own timestamp and message. Add a regression
test covering two timestamped lines in non-follow mode.

ReadJobLogs (non-follow / one-shot tail) returns the whole buffered run as one newline-joined string, which was being sent as a single cdLogEntry. parseCDLogLine then only stripped the timestamp off the first line, leaving every other line's embedded timestamp visible in Message and all lines stamped with the first line's Timestamp. Split the snapshot into individual lines before parsing, same as the follow path already does line-by-line. Addresses CodeRabbit feedback on #2244.

Summary
defang tail/ deploy output showed two near-identical timestamps per Azure CD log line, e.g.ByocAzure.QueryLogsforwarded that raw line verbatim asMessagewhile separately stamping the entry'sTimestampwithtime.Now()— so the tail table's timestamp column and the engine's own timestamp (embedded in the message) both showed, a few milliseconds apart.parseCDLogLineextracts the leading RFC3339Nano timestamp from each CD log line and uses it as the entry'sTimestamp, stripping it (and the-separator) fromMessage. Falls back to the original line +time.Now()when a line doesn't start with a parseable timestamp, so nothing is dropped.defang-cdlog source only — Container App service logs and ACR build logs don't carry this embedded engine timestamp.Test plan
