Add GitHub CLI fallback guidance to Daily Team Evolution Insights workflow prompt

[Copilot]

The Daily Team Evolution Insights workflow (Goose engine) reports github-mcp-server as a missing tool and aborts instead of gathering commits, PRs, issues, and discussions.

Root cause

• Goose has ToolsAllowlist: false capability, so the compiler discards the entire tools: frontmatter section — tools.github.mode/toolsets/cli-proxy settings have no effect for goose workflows.
• Goose's native MCP extension connection to the local gateway (localhost:8080) fails inside the network-isolated sandbox (Failed to start extension 'github'). This is systemic across all goose workflows, not specific to this one — confirmed by the identical warning in a successful comparison run (smoke-goose).
• Regardless of the above, a working github CLI wrapper is always mounted on PATH by the safe-outputs CLI-mount step. In the successful run, the agent discovered it through exploration; in the failing run, it didn't, and gave up.

Fix

• Added an explicit fallback instruction to the workflow prompt telling the agent to try the github CLI wrapper on PATH if the MCP extension/tools fail to load, before reporting a missing tool:

> **Fallback**: If the GitHub MCP tools/extension fail to load (e.g. a "Failed to start
> extension 'github'" warning), a `github` CLI wrapper command is also available on PATH
> as an alternative way to reach the same GitHub MCP tools. Run `github --help` to list
> the available commands (e.g. `list_commits`, `list_pull_requests`, `list_issues`) and
> use `github <command> --param value` to fetch the same data before giving up and
> reporting a missing tool.

Scope

• Workflow-content-only change (.md + regenerated .lock.yml); no compiler/engine code touched.
• The underlying tools-discard behavior for goose and a related CLI-mount filtering gap are broader, systemic issues affecting all goose workflows and are left for a dedicated follow-up rather than bundled into this targeted fix.

• Fixes [aw] Daily Team Evolution Insights is missing required tool #51188
