release v0.1.118

Commit touches ONLY package.json + package-lock.json version fields (0.1.117 → 0.1.118). Part of #772.

Release notes — what ships in v0.1.118

Kernel bump

• acp-kernel 0.0.74 → 0.0.77 (fix: bump acp-kernel 0.0.74 → 0.0.77 (hold acp_cache off wire until adoption) #915). Pulls in three kernel releases: 0.0.75 (cache-reconciliation core acp_cache + buildCacheReport, recommend tail-batch fix, fold-economics exports), 0.0.76 (native Google/Gemini wire codec, recommend range integrity), 0.0.77 (nudge ranges ordered/merged by position, not ref number — fixes [Bug] 消息引用编号与当前顺序不一致时，compress 范围提示会选错消息，导致“内容不足”失败 #887). Host-side: acp_cache is held off every wire surface until adoption lands (给出缓存精确对账，增加新的命令/acp-开头 #800) — the proxy has no execution path for it yet, and an intercepted call would otherwise report a fake success.

Features

• Cross-session search_context: target historical sessions read-only via conversation_id (feat: search_context targets historical sessions read-only via conversation_id #858)
• Configurable output headroom cap: compress.outputHeadroomMaxPct (default 0.25) (feat: configurable output headroom cap (compress.outputHeadroomMaxPct, default 0.25) #898)
• Blind CONNECT tunnels surfaced in logs (CodeBuddy 直接使用httpProxy 不能压缩上下文的问题 #897)
• Request cost observability: per-request inbound size + local processing time logged; outbound size added to the cost line (feat: 在每请求日志中增加 inbound body 大小和本地处理耗时 #903, feat: log per-request inbound size and local processing time #904)

Fixes

• Plugin empty/degenerate-turn retry (Plugin passthrough leaves the client an empty turn when the model echoes a render tag #870, fix(plugin): retry a turn whose only visible output was a stripped tag echo (#870) #871): retry a turn whose only visible output was a stripped tag echo; emit an in-band error when the retry degenerates too; count a dropped tag's interior as degenerate output; rewrite the Responses item id the client already holds; close the retry's abandoned reader
• Echo-imitation swallow: swallow a render tag wrapped around the model's turn (fix(loop): swallow a render tag wrapped around the model's turn #872)
• Preflight round/fold budget (Preflight gives up on a payload far over the window although every fold succeeds #868, fix(preflight): fold deep enough for a payload far over the window (#868) #869): fold deep enough for a payload far over the window; report post-fold size and remaining ranges in the fail-fast 502
• Preflight covered-range recovery: preserve complete content when recovering blocked ranges (fix(preflight): preserve complete content when recovering blocked ranges #668)
• Weak-overflow accounting: counts against demonstrated capability, not trusted-window usage (weak-overflow 低占用盲区：input/window < 0.9 永不计数——相信窗口虚高时保守窗口永远学不出来（真实样本 + 候选修复） #901); a client abort is no longer miscounted as a weak-overflow signal (fix(loop): client abort miscounted as weak overflow signal #910)
• Extracted-trigger pairing: pair text-extracted trigger results as tool-call/tool-result (textProtocol extracted-trigger tool results fall into the marker visibility branch (role:system) instead of tool-call/result pairing #906)
• Launcher proxy-env hygiene: strip inherited proxy vars from launch env for pi/omp/codex/codebuddy ([Suggestion] 建议 launcher 一并覆盖常见小写代理变量（http_proxy / https_proxy） #890) and opencode (fix(launcher): strip inherited proxy vars from opencode/pi/omp/codex/codebuddy launch env (#890) #892), Windows-safe tests included
• plugin-install hardening: guard non-object mcpServers in claude status/remove (fix(plugin-install): non-object mcpServers in .claude.json crashes plugin remove/status (same class as #836) #839) and opencode install/remove/status ([bug] plugin-install opencode: non-object mcp crashes remove/status (irreversible) #836)
• opencode project-bypass warning: warn when opencode project-layer config bypasses the proxy (fix(launcher): warn when opencode project-layer config bypasses the proxy #844)

Pre-flight (same checks as CI)

• npm run typecheck — clean
• npm test — 1741 tests, 1739 pass, 0 fail, 2 skipped (e2e gate)
• npm run build — success
