Document GDL and Miapp development workflows

[mazhelez]

Summary

Documents the local GDL (layers/views) and Miapp development workflows in LOCAL_DEV_ENV.md, ignores generated GDL views, and fixes a git helper used by the Miapp tooling.

Note: This PR intentionally does not change GDLDevelopment.psm1. Automatic configuration of the VSCode launch.json/settings.json during New-GDLView (i.e. without -skipSetupDevelopmentSettings) is currently broken and will be fixed in a follow-up. The docs reflect this by using -skipSetupDevelopmentSettings.

Changes

Documentation (LOCAL_DEV_ENV.md)

• GDL development (layers and views): Explains the layer/view model and the workflow — composing a view with New-GDLView, syncing changes back with Sync-GDLView (incl. -SyncMovesAndDeletes), and cleaning up with Remove-GDLView / Remove-AllGDLViews. Includes the symbolic-link prerequisite (Developer Mode / Administrator) and a note that automatic dev-settings setup is temporarily broken.
• Miapp (propagating changes across layers): Explains what Miapp (Micro Application Integration) does — propagating W1 base-layer changes to dependent country layers — and how to invoke it (Import-Module .\build\scripts\Miapp\MicroApp.psm1 then Invoke-Miapp), with common options and a link to the full Miapp README.

.gitignore

• Ignore the generated GDL App Views (src/Views) so composed views are never committed.

Git helper fix (build/scripts/Miapp/MicroAppGitHelper.psm1)

Get-GitCurrentRemoteBranch relied on a try/catch that never fired: 2>&1 redirected git's stderr into stdout, so fatal: no upstream configured for branch was returned as a normal string instead of raising a terminating error. Now the function inspects $LASTEXITCODE, returning the upstream branch on success, nothing for the expected "no upstream" case, and re-throwing any unexpected error.

Testing

• Get-GitCurrentRemoteBranch returns empty (no throw) on a branch without an upstream.

Copilot PR Review

Iteration 1 · Outcome: no-knowledge

The PR changes only .gitignore, LOCAL_DEV_ENV.md, and a PowerShell module (build/scripts/Miapp/MicroAppGitHelper.psm1); no AL source objects are present in the diff, so no AL knowledge domain applies. al-upgrade-review and al-ui-review returned not-applicable per their own diff-content rules; the remaining four leaves found no AL files to evaluate (no-knowledge).
