Subject: [PATCH 01/11] Optimize CI with dynamic matrix, concurrency groups,
 and cache cleanup (#128)

- Add concurrency groups to cancel in-progress runs on same branch
- Add paths-ignore to skip CI on doc-only changes
- Add pull_request trigger for PRs to main
- Add configure job with dynamic matrix (minimal on feature branches, full on main/PRs)
- Gate Windows builds to full matrix only
- Split macOS into core (always) and full (main/PRs only) jobs
- Update lint/docs conditions to run when optional jobs are skipped
- Update all GitHub Actions to latest versions (checkout v6, cache v5, codecov v6, etc.)
- Add cache cleanup workflows for deleted branches and closed PRs
- Update CodeQL workflow action versions

Closes #128, closes #126, closes #127

Subject: [PATCH 02/11] Address PR review comments: update CI matrix and CodeQL
 workflow

- Ubuntu matrix: add Swift 6.2 and 6.3, remove nightly versions; use 6.3 as single-version for feature branches
- build-macos: keep SPM-only; move macOS Build to build-macos-full
- build-macos-full: add macOS Build with Xcode 26.4; update iOS/watchOS/tvOS/visionOS to Xcode 26.4 / osVersion 26.4
- Add build-android and build-wasm jobs (full-matrix only)
- Update lint and docs needs to include new jobs
- codeql.yml: update runner to macos-26, Xcode to 26.4

Subject: [PATCH 03/11] Restructure ubuntu matrix to include WASM types; fix
 Android matrix

- configure outputs separate ubuntu-os/swift/type arrays (matching MonthBar pattern)
- build-ubuntu composes matrix from all three outputs; wasm/wasm-embedded types
  use swift:6.3-noble container; type and wasmtime-version: 41.0.3 passed to swift-build
- Remove separate build-wasm job
- Android: add swift 6.3 alongside 6.2, add free-disk-space step,
  android-swift-version/android-api-level/android-run-tests parameters, coverage upload

Subject: [PATCH 04/11] Fix full matrix not running on PRs

- configure: guard ci-skip check with event_name check so it always runs on
  pull_request events (github.event.head_commit is null on PRs)
- build-macos: add needs: [configure], gate on configure success so ci-skip
  propagates via dependency chain instead of re-checking head_commit.message

Subject: [PATCH 05/11] Install curl in Swift 6.3 Ubuntu container before
 coverage upload

The swift:6.3 Docker image does not include curl, which is required by
the Codecov uploader. Applies to all 6.3 builds including wasm types.

Subject: [PATCH 06/11] Fix PR trigger for version branches and prevent
 duplicate push/PR runs

- Add version branch pattern to pull_request trigger so PRs targeting
  v0.0.4 (and similar) fire the full matrix CI
- Use github.head_ref || github.ref_name for concurrency group so push
  and pull_request events for the same branch share a group; PR run
  (arrives second) cancels the concurrent push run

Subject: [PATCH 07/11] Fix test file path resolution for WASM/Android/Linux CI

Settings.projectRoot now uses a 3-strategy fallback matching the SyndiKit
pattern: working directory first (reliable for WASM/Android/SPM), then
#filePath-relative (macOS/Linux CI), then walking up parent directories.

Add android-copy-files to copy Documentation.docc to the Android emulator's
working directory so the path resolution finds the files via Strategy 1.

Subject: [PATCH 08/11] Limit doc test paths on WASM to tutorial files only

Examples/ (2.1MB) and full Documentation.docc (with images) exceed WASM
memory constraints. On WASI, use only the two lightweight tutorial .md files
(~36KB total). Matches SyndiKit's #if os(WASI) subset pattern.

Subject: [PATCH 09/11] Fix Android/WASM doc path resolution and coverage
 conditions

- Add Strategy 1b to Settings.projectRoot: detect Documentation.docc/ in
  working dir (android-copy-files copies last component only)
- Add #if os(Android) branch to docPaths with prefix-less paths matching
  the flat copy layout on Android devices
- Add id: build to swift-build steps and gate coverage upload/processing
  on steps.build.outputs.contains-code-coverage == 'true' across all jobs
