Fixes #60

[Copilot]

🟡 Changes recommended

The workflows reference GitHub Actions major versions that appear to be invalid/nonexistent (e.g., actions/cache@v6, actions/stale@v11, codecov/codecov-action@v7), which would break CI.

Pull request overview

This PR updates coroutine caller management to resume multiple waiters in registration (FIFO) order (instead of hash iteration order), aligning behavior between the C++20 coroutine backend and the stackful channel backend and making wake-up order deterministic.

Changes:

• Replace unordered multi-caller storage with an order-preserving container (list + hash index) for FIFO resume order.
• Add unit tests that assert FIFO wake-up ordering for both task futures and stackful channels.
• Update documentation dependencies and refresh GitHub Actions workflow versions.

File summaries

File	Description
test/case/task_promise_test.cpp	Adds a FIFO-order test for multiple callers awaiting the same task future.

#	Severity	Category	Location	Message
0	LOW	correctness	CHANGELOG.md:3	本次变更在 CHANGELOG.md 新增 ## 2.3.3 版本条目，但 CMakeLists.txt 第 27 行的 project(... VERSION "2.3.2") 未同步升级。该仓库既有惯例是同一提交内同时修改两处（经 git 历史核实：2.3.0 于 04486f5、2.3.1 于 5642a6e、2.3.2 于 e76d9b6 均为同提交成对变更）。若按此分支发布 2.3.3，生成的 libcopp_build_features.h 中 LIBCOPP_VERSION、安装/包管理元数据仍报告 2.3.2，下游 find_package(libcopp 2.3.3) 等版本检查会失败。最小修复：将 CMakeLists.txt 的 VERSION 提升为 2.3.3。

Code reference: CHANGELOG.md:3

# CHANGELOG

## 2.3.3

1. Resume multiple callers of `promise_caller_manager` (C++20 coroutine) and `stackful_channel_context_base`
