Dependency injection

[matt-edmondson]

Continue the work that has been progressing in the dependency-injection-3 branch with the intention of completing it and merging into main.

The branch this points at is stale. Current state of the DI branches:

Branch	Last commit
origin/dependency-injection-1	2025-07-18
origin/dependency-injection-3 (named in this issue)	2026-01-19
origin/copilot/complete-dependency-injection	2026-01-31
origin/dependency-injection-2	2026-06-13
feature/essentials-di	2026-08-17

main still has no DI — no ServiceCollection/ServiceProvider/AddSingleton in BlastMerge.ConsoleApp/Program.cs. So the goal stands, but the work has moved on twice since this was filed; feature/essentials-di is the live line, not dependency-injection-3.

Worth updating the body to name feature/essentials-di and deleting the four abandoned branches so the next person doesn't pick the wrong one.

Triage — update

Priority: Medium Effort: Large

What's changed since the last comment: Confirmed still true — main has no DI (ServiceCollection/ServiceProvider/AddSingleton all absent from BlastMerge.ConsoleApp/Program.cs), and the PR this issue's own "closed by" reference points to (#6) is closed, not merged. feature/essentials-di (last commit 2026-08-17) remains the most current line per the prior comment; the four older DI branches are stale.

What needs to be done: Pick up feature/essentials-di, finish wiring ServiceCollection/DI through the console app, and merge to main.

Suggested next steps / acceptance criteria:

• Confirm feature/essentials-di is still the intended branch (re-check for anything newer before resuming)
• Delete the four abandoned branches (dependency-injection-1, dependency-injection-2, dependency-injection-3, copilot/complete-dependency-injection) once confirmed superseded, so the next contributor doesn't pick the wrong one
• Update the issue body to name the current branch instead of dependency-injection-3

Blockers / dependencies: None identified beyond branch selection/cleanup noted above.
