[bot] Update course for Copilot CLI v1.0.22–v1.0.28 changes

[DanWahlin]

What was found

Reviewing GitHub Copilot CLI releases from April 9–16, 2026 (v1.0.22 through v1.0.28), three beginner-relevant changes were identified that were not yet reflected in the course content on main:

1. v1.0.26 — "Steering" renamed to "remote control" in --remote//remote help text and documentation
2. v1.0.25 — /add-dir now accepts relative paths (e.g. ./src, ../sibling) in addition to absolute paths
3. v1.0.22 — Custom agents can now declare a skills field to eagerly load skill content into agent context at startup

Note: Other recent additions (/ask, /env, --plan, --autopilot, /remote, .mcp.json migration, plugin marketplace update, MCP from registry) were already present in the main branch.

What was updated

Chapter 01: First Steps (01-setup-and-first-steps/README.md)

• Updated the remote sessions tip to use the current "remote control" terminology instead of the older "steer" wording (aligns with v1.0.26 rename)

Chapter 02: Context and Conversations (02-context-conversations/README.md)

• Added a callout in the /add-dir troubleshooting section noting that relative paths (./src, ../sibling-folder) are now supported and resolved automatically

Chapter 04: Agents and Custom Instructions (04-agents-custom-instructions/README.md)

• Added skills as an optional property in the agent frontmatter reference table
• Updated the "Required vs Optional" inline note to include skills
• Added a tip explaining how the skills field lets agents pre-load specific skills into context at startup (bridges the agents-and-skills concepts across Ch04 and Ch05)
