docs: guides section overhaul — fix existing + add 3 new tutorials (#5735)
* docs: fix guides section — sidebar ordering, broken links, position conflicts
- Add local-llm-on-mac.md to sidebars.ts (was missing after salvage PR)
- Reorder sidebar: tips first, then local LLM guide, then tutorials
- Fix 10 broken links in team-telegram-assistant.md (missing /docs/ prefix)
- Fix relative link in migrate-from-openclaw.md
- Fix installation link pointing to learning-path instead of installation
- Renumber all sidebar_position values to eliminate conflicts and match
the explicit sidebars.ts ordering
* docs: add 3 new guides — cron automation, skills, delegation
New tutorial-style guides covering core features:
- automate-with-cron.md (261 lines): 5 real-world patterns — website
monitoring with scripts, weekly reports, GitHub watchers, data
collection pipelines, multi-skill workflows. Covers [SILENT] trick,
delivery targets, job management.
- work-with-skills.md (268 lines): End-to-end skill workflow — finding,
installing from Hub, configuring, creating from scratch with reference
files, per-platform management, skills vs memory comparison.
- delegation-patterns.md (239 lines): 5 patterns — parallel research,
code review, alternative comparison, multi-file refactoring,
gather-then-analyze (execute_code + delegate). Covers the context
problem, toolset selection, constraints.
Added all three to sidebars.ts in the Guides & Tutorials section.
