docs(changelog): add PR 14577 release note (openclaw#14577) (thanks @DylanWoodAkers)

Apply OpenAI's recommended pattern for skill descriptions:
- Add 'Use when' conditions for clear triggering
- Add 'NOT for' negative examples to reduce misfires
- Make descriptions act as routing logic, not marketing copy

Based on: https://developers.openai.com/blog/skills-shell-tips/

Skills updated:
- coding-agent: clarify when to delegate vs direct edit
- github: add boundaries vs browser/scripting
- weather: add scope limitations

Glean reported 20% drop in skill triggering without negative
examples, recovering after adding them. This change brings
Clawdbot skills in line with that pattern.

 ### Changes
 
+- Skills: refine skill-description routing boundaries with explicit "Use when"/"NOT for" guidance for coding-agent/github/weather, and clarify PTY/browser fallback wording. (#14577) Thanks @DylanWoodAkers.
 - Agents/Subagents: add an accepted response note for `sessions_spawn` explaining polling subagents are disabled for one-off calls. Thanks @tyler6204.
 - Agents/Subagents: prefix spawned subagent task messages with context to preserve source information in downstream handling. Thanks @tyler6204.
 - iMessage: support `replyToId` on outbound text/media sends and normalize leading `[[reply_to:<id>]]` tags so replies target the intended iMessage. Thanks @tyler6204.
