feat(nuitka): add Nuitka --onefile migration design

Sodawyx · claude · Sodawyx · commit 66e2e62f5893 · 2026-04-22T10:06:45.000+08:00
Switches the CLI binary toolchain from PyInstaller to Nuitka so warm
invocations hit the payload-hash cache at ~/.agentrun/cache/ and avoid
the ~2s per-call re-extraction, unblocking the agent-hot-path scenario.

 After installation, both `ar` and `agentrun` are available as entry points and behave
 identically. `ar` is shorter; the examples in this manual use it.
 
+### Binary startup cache
+
+The prebuilt binary is a Nuitka `--onefile` executable. On first launch it extracts its payload into `~/.agentrun/cache/agentrun-<version>/` (about 20 MB); subsequent launches reuse the cache, bringing warm start-up below 300 ms.
+
+- **Safe to delete.** Remove `~/.agentrun/cache/` at any time; the next invocation re-extracts.
+- **Upgrades.** A new binary version writes to a new subdirectory; old ones stay until you clean them up.
+- **Read-only `$HOME`.** If `~/.agentrun/cache/` is not writable, the bootstrap falls back to `$TMPDIR` with full re-extraction on every run (~2 s). Either grant write access or run from a shell where `$HOME` points somewhere writable.

+### 二进制启动缓存
+
+预编译二进制是一个 Nuitka `--onefile` 可执行文件。首次运行会把内置 payload 解压到 `~/.agentrun/cache/agentrun-<version>/`（约 20 MB），之后每次启动复用缓存，热启动耗时低于 300 ms。

+- **可以随时删除。**`~/.agentrun/cache/` 删掉后下一次运行自动重建。

+- **`$HOME` 只读的情况。**若 `~/.agentrun/cache/` 不可写，bootstrap 会回落到 `$TMPDIR` 且每次都完整解压（~2 秒）。请确保目录可写，或从 `$HOME` 指向可写位置的 shell 启动。
