Local mage preflight cspell does not cover docs/misc files (CI cspell-misc gap)

[jongio]

Summary

mage preflight runs cspell only on **/*.go files using .vscode/cspell.yaml, but CI also runs a separate cspell check on docs and miscellaneous files using .vscode/cspell.misc.yaml (workflow: .github/workflows/cspell-misc.yml). This means changes to docs/, SECURITY.md, README.md, and other non-Go files can pass local preflight but fail CI cspell.

Root Cause

Check	Glob	Config	Scope
Local mage preflight	**/*.go	.vscode/cspell.yaml	Go source only
CI cspell-misc.yml	**/*	.vscode/cspell.misc.yaml	Everything except cli/, ext/, templates/, eng/

The local preflight step (magefile.go line 221) only passes **/*.go to cspell. There is no local equivalent of the CI cspell-misc.yml workflow.

Impact

Developers adding or editing docs (e.g., architecture specs under docs/) will not see cspell failures locally. This was discovered on PR #7603 where 37 cspell errors in docs/azd-down-resource-group-safety/architecture.md passed local preflight but failed CI.

Proposed Fix

Add a second cspell pass in mage preflight (magefile.go) that mirrors the CI cspell-misc.yml workflow:

// 5b. Spell check (cspell - misc files)
fmt.Println("══ Spell check (cspell-misc) ══")
if err := runStreaming(repoRoot, "cspell", "lint", "**/*",
    "--relative", "--config", "./.vscode/cspell.misc.yaml", "--no-progress"); err != nil {
    record("cspell-misc", "fail", err.Error())
} else {
    record("cspell-misc", "pass", "")
}

This should run from the repo root (not cli/azd/) to match the CI behavior.
