Oliver Kieselbach 09492e908c fix(security): IME log-pattern pack is anchored and linear (all 90 patterns start with ^, IME-APP-VERSION spells the report-delta JSON out instead of a chained [^}]*? scan) and the ImeLogTracker read loop is bounded — BoundedLineReader (32 MB per line, evidence: real 5.6 MB "Get policies" lines; exact byte bookmarks, no decoder read-ahead loss on cancel), 2 s per-line matching budget across all patterns, held-back unterminated EOF tails (≤1 MB, 1 s settle) instead of dropping them and raw-matching fragments, a complete entry after a dropped one is no longer swallowed as its close, one Warning per pass (oversizedLines/regexTimeouts/lineBudgetBreaks) instead of silent Debug timeouts; unanchored PS-SCRIPT-CONTEXT false positives on [Win32App] SideCarScript… lines (which overwrote the pending platform script's RunContext) are gone; --run-ime-matching assembles multiline entries like the tracker

Oliver Kieselbach a3089753d3 IME patterns: repair drift found by decompiled-source audit (IME 1.97 Dec-25)
Audit vs decompiled IME 1.97.107: ~55/79 patterns verified verbatim, but
several were broken or dead against the current V3 pipeline.

Fixes:
- IME-ESP-TRACK-STATUS: drop trailing anchor (line grew ' with name: <n>.')
- HS-COMPLIANCE: tolerate both 'remdiation' typo and corrected wording;
  new HS-COMPLIANCE-POST for the reworded post-detection line
- IME-DETECTION-RESULT: capture DetectedDifferentVersion (ordered first)
- IME-ENFORCEMENT-SUCCESS: unpin OldValue (Error/PendingReboot/null paths)
- IME-ERROR-REPORT: allow unquoted null OldValue on first write
- Disable 11 dead patterns (emitters removed with IME's old V1/V2 pipeline;
  IME-DETECTED-OLD additionally collided with IME-SKIP-INSTALL-DETECTED)

New signals (existing actions, tailed files only):
- IME-ESP-APP-REGISTERED + IME-CACHE-MISS as app-name sources (replacing
  dead IME-UPDATE-NAME-1/2/3)
- IME-WINGET-ERROR (WinGet failures were invisible)
- IME-EXITCODE-MAPPED-FAILED (normal mapped-exit-code failure path)
- IME-STOP-SIGNAL (service stop != OS shutdown)
- IME-RESTART-STOP-PROCESSING (reboot-gated processing abort)

Backend seed diff now also compares Enabled + Parameters - enable/disable
flips and parameter changes previously never propagated to the table.

All exact wordings verified against decompiled source; regex smoke-tested
via validate-ime-patterns.py (engine=regex, 75/75 compiled, all new
patterns fire on synthetic lines with the exact IME format strings).
