fix: default selfImprovement.enabled to true when config block omitted

[AliceLJY]

Summary

• When selfImprovement config block is entirely omitted from plugin config, enabled defaults to false, which prevents all three self_improvement_* tools from registering
• This is inconsistent: when the block IS provided but enabled is not explicitly set, it correctly defaults to true via the !== false check
• Fix: change the else-branch default from enabled: false to enabled: true so the behavior is consistent regardless of whether the config block is present

Details

In index.ts around line 3830, the config parsing for selfImprovement has two branches:

1. When selfImprovement is an object: enabled defaults to true (via !== false)
2. When selfImprovement is omitted: enabled was hardcoded to false (the bug)

Verified by testing on a live OpenClaw instance: adding selfImprovement: { enabled: true } to the config makes all 3 self-improvement tools appear, confirming the tools work — they just weren't registering due to the default.

Fixes #375

这个修复方向是对的，我这边没有看到阻塞合并的问题。它确实命中了 #375 的核心原因：selfImprovement 整块省略时，enabled 被落成了 false，导致 self_improvement_* 工具不注册；把这里改成 true 之后，这条路径就和 issue 里的复现对上了。

我只想补一个非阻塞备注：selfImprovement 这组默认值现在仍然有一点不一致。当前 PR 修了 enabled，但在“整块 block 省略”时， beforeResetNote / skipSubagentBootstrap / ensureLearningFiles 仍然会落成 false；而如果传 selfImprovement: {}，这三项又都会是 true。如果你想把这组语义彻底拉齐，后续可以顺手把这三个 sibling flag 也一起对齐到同一路径行为。

Good catch — just pushed a follow-up commit (dea7079) that aligns the three sibling flags (beforeResetNote, skipSubagentBootstrap, ensureLearningFiles) to also default to true when the selfImprovement block is omitted. Now both paths produce identical defaults.
