fix: apply swift-format strict lint baseline across all Swift files

[Copilot]

• Explored repository structure and identified formatting issues
• Created .swift-format configuration with 4-space indentation
• Ran swift format format --in-place on Package.swift, Sources/, and Tests/
• Ran formatter on PromptRefactorApp Swift files
• Renamed GroqModel enum cases to proper lowerCamelCase (llama318bInstant, llama3370bVersatile)
• Verified all files pass swift format lint --strict (exit code 0)
• Resolved merge conflict by incorporating master's functional changes:
  • clarifyPrompt now preserves parenthesized content (bug fix from PR fix: preserve parenthesized content in clarifyPrompt #16)
  • Accessibility polling loop properly handles task cancellation via do/catch (from PR Fix accessibility polling loop ignoring task cancellation #14)
  • Updated + added tests for new clarifyPrompt behavior
• All 9 tests pass with no regressions

This section details on the original issue you should resolve

<issue_title>Repository fails strict swift-format lint baseline</issue_title>
<issue_description>## Problem
The repository currently fails the documented strict formatter checks, including indentation, trailing commas, and line-length findings across package, source, and test files.

Impact

• Style drift and noisy diffs.
• Harder code reviews and inconsistent contributor experience.
• CI lint adoption is blocked until baseline is fixed/suppressed.

Evidence

Commands run from repo root:

• swift format lint --strict Package.swift
• swift format lint --strict --recursive Sources Tests PromptRefactorApp

Both return many violations.

Recommendation

• Run swift format format --in-place across tracked Swift files and commit as a dedicated formatting pass.
• Optionally add a formatter configuration and CI gate to prevent drift.
• If full reformat is too large, phase by module with temporary lint scope controls.</issue_description>

Resolved in da89a79. The merge conflict was caused by two PRs that had been merged into master:

• PR fix: preserve parenthesized content in clarifyPrompt #16 (clarifyPrompt fix): Incorporated — parenthesized content is now preserved instead of stripped. Updated the affected test and added the new clarifyPromptPreservesSemanticParentheticalContent test.
• PR Fix accessibility polling loop ignoring task cancellation #14 (accessibility polling): Incorporated — the .task loop now uses do { try await Task.sleep(...) } catch { return } to properly exit on task cancellation.

All 9 tests pass and swift format lint --strict still exits 0 for all targets.
