fix: detailed bug check and fixes (v1.1.0)

Compile-level fixes:
- common.h: add stdint.h (uint8_t was undefined, fatal compile error)
- utils.c: add sys/stat.h (struct stat/stat/mkdir)
- add include/isup_sdk.h declaring all NET_E* SDK interfaces, fixing
  implicit-declaration hard errors (GCC14) in stream.c/alarm.c/playback.c
- Makefile: move BUILD_DIR before OBJECTS (:= expands empty otherwise),
  align simulate macro with code, add missing test target

Runtime / memory-safety fixes:
- main.c rewritten: remove duplicate/missing goto labels; join heartbeat
  and simulation threads on shutdown; async-signal-safe handler
  (volatile sig_atomic_t + sigaction)
- stream.c/playback.c: compaction-based remove no longer drops the adjacent
  session; cache id before free() to fix use-after-free
- config.h: pid_file int[] -> char[MAX_PATH_SIZE]
- main.c: unify PID file write/delete path; guard fps<=0 divide-by-zero

Feature additions:
- -test full-chain self-test (register -> push -> playback -> alarm -> logout)
- make test target
- wire previously-unused helpers: alarm_ingest, stream_get_session,
  stream_find_by_channel, playback_get_session, pack_h264_to_ps

Verified on Ubuntu 24.04 / GCC 14: make simulate = 0 warnings / 0 errors;
./hikvision-isup-client -test passes, exits cleanly (exit 0).

+
+## [1.1.0] - 2026-10-08
+
+### 修复 (Fixed)
+- common.h 缺少 `<stdint.h>` 导致 `uint8_t` 未定义，编译失败 (B1)
+- main.c 重复/缺失 goto 标签导致编译失败；重写为单一 teardown 状态机 (B2)
+- main.c 后台线程未 join 造成退出崩溃；信号处理非 async-signal-safe (B3)
+- Makefile `BUILD_DIR` 定义顺序错误、仿真宏与代码不一致、缺失 test 目标 (B4)
+- stream.c/playback.c 数组压缩删除丢失相邻会话，造成泄漏与失联 (B5)
+- stream.c/playback.c `free()` 后读取字段的 use-after-free (B6)
+- config.h `pid_file` 类型错误 (B7)
+- utils.c 缺少 `<sys/stat.h>` (B8)

+- `./hikvision-isup-client -test` 全链路通过，进程干净退出(exit 0)
+
+## [1.0.0] - 初始版本

+## 版本与修复说明
+
+### v1.1.0 — 详细 Bug 检查与修复 (2026-10-08)
+
+本次对完整工程逐文件做了编译级 / 内存安全级 / 逻辑级排查，共修复 **9 类** 问题，
+并在 Ubuntu 24.04 (GCC 14) 下验证 `make simulate` **零 warning、零 error** 通过，
+`./hikvision-isup-client -test` 全链路自测通过、进程干净退出(后台线程全部回收)。
+
+| 编号 | 文件 | 严重级别 | 问题 | 修复 |
+|------|------|----------|------|------|
+| B1 | common.h | 致命(编译失败) | 大量使用 `uint8_t` 却未包含 `<stdint.h>` | 增加 `#include <stdint.h>` |
+| B2 | main.c | 致命(编译失败) | `cleanup_stream`/`cleanup_platform` 标签重复定义；`goto cleanup` 指向不存在标签 | 重写为单一 `teardown` + 各模块 `*_ok` 状态位逆序清理 |
+| B3 | main.c | 致命(运行崩溃) | 心跳/模拟线程创建后从不 join，退出即访问已释放资源；信号处理函数调用 `fprintf/localtime` 非 async-signal-safe | 线程句柄提为文件作用域并在退出时 join；信号处理仅置 `volatile sig_atomic_t` 标志，致命信号改回默认行为，改用 `sigaction` |
+| B4 | Makefile | 致命(构建错乱) | `BUILD_DIR` 在 `OBJECTS` 之后定义，`:=` 即时展开使目标路径为空；`simulate` 宏 `HAVE_HIKVISION_SIMULATION` 与代码判断的 `HAVE_HCNETSDK` 不一致；声明了 `test` 却无规则 | `BUILD_DIR` 前移；仿真分支统一宏；补齐 `test` 目标 |
+| B5 | stream.c / playback.c | 高(内存泄漏/失联) | `remove_session`/`remove_playback` 先把目标置 NULL 再从头压缩，连带丢弃目标之后的第一个会话 | 改为逐元素搬运、命中者丢弃，不丢元素 |
+| B6 | stream.c / playback.c | 高(use-after-free) | `free(session)` 之后仍读取 `session->stream_id`/`playback_id` 打印 | free 前用局部变量缓存 id |
+| B7 | config.h | 中 | `pid_file` 误声明为 `int[]`，却当字符串使用 | 改为 `char[MAX_PATH_SIZE]` |
+| B8 | utils.c | 中(编译/运行) | 使用 `struct stat`/`stat`/`mkdir` 却未包含 `<sys/stat.h>` | 增加头文件；补全 `ensure_directory` |
+| B9 | platform.c/stream.c/alarm.c/playback.c | 中(编译失败,GCC14) | `NET_E*` SDK 函数仅在 platform.c 局部 extern，其它 .c 调用触发隐式声明错误；`sleep_milliseconds` 无声明 | 新增 `include/isup_sdk.h` 集中声明，各 .c 统一包含；utils 原型并入 common.h |
+| 附带 | main.c/stream.c/playback.c | 低 | PID 写入路径与删除路径不一致(残留)；`add_unack_alarm`/`find_session`/`find_playback`/`pack_h264_to_ps` 定义了却从未调用；模拟线程 `fps<=0` 除零 | 统一 PID 路径；新增 `alarm_ingest`/`stream_get_session`/`stream_find_by_channel`/`playback_get_session` 并接入；PS 封装在 `stream_send_frame` 中实际调用；fps 兜底 |
