release v0.1.45

[ranxianglei]

Release v0.1.45 from master (version bump only; content below already merged).

Changes since v0.1.44

acp-kernel 0.0.31 → 0.0.32 (#184)

• KEEP_LAST_ORPHANED 0 → 2 (kernel release v0.1.33 #104, reverts release v0.1.6 #18): the newest two orphaned compress call+result pairs stay visible in the sent view.
• Restores compress-failure observability and removes the fixed-point precondition behind the infinite no-op compress loop — with failed calls visible again, the sent view changes on every retry, so a deterministic model can no longer sit pinned at an unobservable fixed point.
• Residue bounded at 2 pairs in all pipeline paths; release v0.1.6 #18's unbounded accumulation does not return.
• Test updated: tests/plugin-protocol.test.ts — the consumed compress tool_use is now kept visible (orphaned, KEEP_LAST_ORPHANED=2) instead of hidden; folding assertions unchanged.

tsup inlines the kernel into dist, so this release is the only way users get 0.0.32.

Pre-flight (on master, which this branch is based on)

• npm run typecheck — clean
• npm test — 512/512 pass (3 consecutive runs)
• npm run build — success (dist/index.js 2.12 MB, contains KEEP_LAST_ORPHANED = 2)

Merging publishes to npm via release.yml (tag v0.1.45).
