Align CLI help/docs consistency for outcomes, project setup, URLs, and wording

[Copilot]

CLI consistency inspection found doc/help drift in four command surfaces: missing reference entries, an auth-doc host mismatch, whitespace artifacts in help text, and transport wording mismatch.

• CLI reference completeness (docs/src/content/docs/setup/cli.md)

  • Added missing gh aw outcomes command documentation with examples and options.
  • Added missing --with-project-setup coverage under gh aw project new (example + option).

• Project auth URL consistency (pkg/cli/project_command.go)

  • Updated help text docs link host from github.github.io to github.github.com to match configured site host.

• Forecast help text cleanup (pkg/cli/forecast_command.go)

  • Removed duplicate double spaces in the long description to normalize rendered help output.

• MCP server wording consistency (pkg/cli/mcp_server_command.go)

  • Updated --port example text to explicitly state SSE transport, matching command semantics in the long description.

• Regression coverage (focused help-text assertions)

  • pkg/cli/project_command_test.go: asserts correct auth URL host.
  • pkg/cli/forecast_test.go: guards against reintroducing duplicate spacing in key long-description phrases.
  • pkg/cli/mcp_server_command_test.go: asserts SSE wording in mcp-server port example.

# Newly documented command surface in CLI docs
gh aw outcomes 1234567890 --outcomes-dir ./otlp
gh aw project new "Project Q1" --owner myorg --with-project-setup
