Adds a tree-sitter-based Swift parser (repository scan, function/type extraction, call-graph construction with overload/trailing-closure/actor resolution, reachability filtering, analysis-unit generation), integrated into the post-#199 registry architecture: a single config/languages.json entry provides dispatch, CLI --language choice, markdown fence, Go flag help and detection. Adds Swift @objc/@IBAction entry-point + XPC/CLI input detection, the .swift context-corrector extension, the tree-sitter-swift dependency, per-unit reachability prune telemetry, and the Swift test suite.

Summary
Adds a Swift language parser to OpenAnt, integrated via the
config/languages.jsonregistry introduced in #199. A single registry entry (subprocess mode) provides
parser dispatch, the
--language swiftCLI choice, the markdown fence, Go flaghelp, and language detection — no per-language dispatch edits.
What's included
libs/openant-core/parsers/swift/): tree-sitter-based repositoryscan, function/type extraction, and call-graph construction — overload resolution,
trailing-closure argument labels (SE-0279), actor / protocol / extension handling,
and cross-file method resolution — followed by reachability filtering and
analysis-unit generation. Adds the
tree-sitter-swiftdependency.config/languages.json):swift→ subprocess parserparsers/swift/test_pipeline.py,.swiftextension,swiftfence, Xcodebuild-dir skip entries.
entry_point_detector.py): Swift@objc/@IBActionroots and XPC / CLI / stdin input surfaces (
CommandLine.arguments,NSXPCListener,readLine,NWListener, …) — additive, Swift-syntax-scoped.context_corrector.py):.swiftadded to source gathering.hook in the core reachability filter (does not alter feat: repository-supplied threat models, application-type context, and multi-language scanning #199's blackout behavior).

unreachable code).
Notes
The Swift call graph keeps cross-file calls to user methods whose names shadow
Swift built-ins (e.g.
filter,map); without this the method — and its wholereachable subtree — would be dropped from analysis. Swift emits forward-slash
relative paths for cross-platform unit-ID stability.
