Align log file format with the shared convention and add 30-day retention - #9

…tion Log file lines are now written as "[yyyy-MM-dd HH:mm:ss] LEVEL message" in local time, with the level padded to five characters and limited to DEBUG, INFO, WARN and ERROR. Session header and structured section lines are emitted as INFO lines in the same format; WARNING maps to WARN and SUCCESS is an INFO line. Fractional seconds are dropped from the timestamp. At logger initialisation, .log files in the logs directory older than 30 days are removed. The sweep is non-recursive and skips anything it cannot inspect or delete. The CLI no longer writes a startup log under /tmp before the logger exists. It creates the real logs directory up front and reports a failure to do so on stderr. The log viewer's line colouring is updated for the new level labels, and tests cover the line format and the retention sweep against a temporary directory.

Summary
[yyyy-MM-dd HH:mm:ss] LEVEL message(local time, level padded to five characters, onlyDEBUG,INFO,WARN,ERROR). Session header and structured section lines are written asINFOlines in the same format;WARNINGmaps toWARN,SUCCESSbecomesINFO. Fractional seconds are dropped..logfiles in/Library/Managed Bootstrap/logsolder than 30 days are removed. The sweep is non-recursive and tolerates files it cannot inspect or delete./tmpbefore the logger exists. It creates the real logs directory up front and reports a creation failure on stderr.Testing
swift buildsucceeds with no new warnings.swift test: 25 tests in 5 suites pass, including new tests for the line format, for every line of a freshly initialised log file matching the convention, and for the retention sweep against a temporary directory./Library/Managed Bootstrap/logs(requires root).
