test(agent): real two-writer-era CMTrace fixture from session e9753578

Browse Source 
Captured from ImeLogs/AgentExecutor.log of the session that exposed the regression
(agent 2.0.1410; device booted on the Pacific OOBE default, agent set W. Europe at
12:13:22Z).

One file, two writer eras: 371 lines rendered at local hour 05 by a writer still
on PDT (UTC-7) and 195 at hour 14 by one already on CEST (UTC+2) - nine hours
apart, interleaved, and no line carries a bias suffix, so nothing in the file
itself says which is which. Exactly the case the per-file calibration could not
express, and the test that was missing.

Analysing the archive also turned up a SECOND, independent defect the revert
commit did not know about: the agent log reports "IntuneManagementExtension.log
writer offset measured 02:00:00" while that file contains ONLY hour-05 lines
(2022 of them, zero at hour 14). A +2 measurement is impossible from its own
content, so the calibration anchor leaked across file boundaries - files are
walked in sorted order and AgentExecutor.log precedes it. Two-eras-per-file and
anchor-leak are separate bugs; both must be fixed.

Extension is .cmtrace.txt, not .log: *.log is globally gitignored, and a fixture
has no reason to claim that extension.

Fixture only, nothing consumes it yet - the era-aware calibrator is next.

# Real CMTrace lines from session e9753578-b1d8-4188-9151-7545be7e1761 (agent 2.0.1410).
# ImeLogs/AgentExecutor.log - ONE file, TWO writer eras.
#
# The device booted on the Pacific OOBE default; the agent set W. Europe at 12:13:22Z.
# Lines at local hour 05 were rendered by a writer still on PDT (UTC-7), lines at hour 14
# by one already on CEST (UTC+2) - 9 hours apart, interleaved in the same log. No line
# carries a bias suffix, so nothing in the file itself says which is which.
#
# This is the case that broke the per-file calibration: the anchor is the newest line, so
# its offset was applied to the older era too. Any era-aware calibrator must resolve BOTH
# halves of this file correctly.
#
# era PDT (local 05:xx): 371 lines in the original, era CEST (local 14:xx): 195
