[ranxianglei]

Summary

Stable release v1.14.9 covering 3 PRs since v1.14.8.

PRs Included

1. fix: remove context-relative suppression from filterRecommendedRanges (Issue #251) #252 — Two fixes: (1) Issue Bug: filterRecommendedRanges hides valid compression ranges at large context windows #251: filterRecommendedRanges suppressed ALL recommendations when compressible content was below 5% of modelContextLimit. Rewrote to always show all ranges. (2) Nudge loop fix: lastNudgeShownTokens reset to undefined on nothingToCompress caused nudges firing every turn.
2. chore: bump context-compress-algorithms to 1.3.0 #257 — Bump context-compress-algorithms 1.2.1 → 1.3.0. Holistic TIER2/TIER3 prompts — summarize by theme instead of per-block, fixing length overflow with 70+ T1 blocks (issue [Bug] Tier 2/3 nudge 建议单个全量压缩范围，大会话必超 summary 上限导致卡死 #256).
3. docs: document multi-entry compress format in system prompt and T2/T3 nudge #259 — Document multi-entry compress format in system prompt and T2/T3 nudge. The compress tool already supported content arrays (PR feat: batch compress with per-entry topics #156), but only single-entry was shown for block-based compression.
