Release commit bumps 0.1.99 → 0.1.100 (package.json + package-lock.json only).

Ships since v0.1.99:

• fix #648: add hostUsageCredit switch to opt out of #408 host-usage backfill #649 — hostUsageCredit switch ("auto" | "off", env BILI_HOST_USAGE_CREDIT) lets plain proxy clients (ZCode, ZCode 宿主 usage 回填未压缩基线:压缩后上下文显示成累加值,非实际转发量(v0.1.88 起;#645 的 ZCode 面) #648) opt out of the 代理压缩不上报改写量,宿主上下文会计塌缩至 ~0(omps recordAnchoredHistoryRewrite 零调用);且持久化 lastInputTokens 恢复无钳制,旧版负值升级后复活 #408 uncompressed-baseline usage backfill; default auto = no behavior change. 1270 tests / typecheck / build green.

Merge → CI publishes 0.1.100.

Diff cleanliness (first gate) ✅

• Exactly one commit vs master: 52e2685 release v0.1.100 on branch 2026-09-10_release-v0.1.100.
• Diff is version fields only: package.json (+1/-1) and package-lock.json (+2/-2), both 0.1.99 → 0.1.100. Nothing else touched — no content bundled into the release commit, per the one-version-one-commit rule.
• Base is current master @ 175beb2 (includes fix #648: add hostUsageCredit switch to opt out of #408 host-usage backfill #649 hostUsageCredit, the only change since v0.1.99). GitHub reports mergeable, no conflicts.
• npm registry check: latest published is 0.1.99, so 0.1.100 is free — no collision.

Pre-flight on head commit 52e2685 (same checks CI runs) ✅

• npm run typecheck: clean
• npm test: 1270 pass / 0 fail (matches the 1270-test count in the PR body)
• npm run build: success (self-contained dist/index.js)
