Alex Hoppen b4fafb64b3 Fix build warnings
Fix all build warnings except those caused by using old DocC request/response types, which are a little harder to resolve.

Alex Hoppen facfb28d39 Don’t implicitly cancel requests when an edit is detected
Instead, use `staleRequestSupport.retryOnContentModified` as an indicator which requests should return a `ContentModified` error when the document is modified. This fixes https://github.com/swiftlang/sourcekit-lsp/issues/2136 by no longer implicitly cancelling inlayHints in Helix while still implicitly cancelling semantic tokens request, which was the motivation for https://github.com/swiftlang/sourcekit-lsp/pull/1629.

Fixes #2136

Rintaro Ishizaki 64aa354caf [TestDiscovery] "/refresh" style tests/playgrounds requests
When the client opts in to `workspace/tests/refresh` or
`workspace/playgrounds/refresh` via experimental client capabilities,
SourceKit-LSP now maintains a proactive cache of the current test and
playground lists and sends the corresponding `workspace/.../refresh`
notification whenever the cache changes. `workspaceTests()` /
`workspacePlaygrounds()` then serve subsequent fetch requests directly
from the cache.

Add `EntryPointManager`: runs background scans, stores the results,
fires callbacks on changes:
 - Start scanning when build targets are updated including initial
   updates, any watched files are changed, and index is updated.
 - Send '/refresh' server initiated requests when the cache has changed.
 - Coalesces rapid invalidations by cancelling any in-flight refresh task.

Also:
- Simplify `SourceKitIndexDelegate` from an `actor` with `AtomicInt32`
  to a plain `class`, since it is only called from IndexStoreDB's
  internal serial dispatch queue.

Alex Hoppen 9d7e7f3c30 Provide semantic functionality in copy destinations
If we have a source item `include/Test.h` that gets copied to `build/Test.h`, we currently don’t provide any semantic functionality for `build/Test.h`. Improve the build settings fallback logic to construct fallback build settings for `build/Test.h` based on `include/Test.h`.

Rintaro Ishizaki 1c99daabef [TestDiscovery] Prefer syntactic scan results over semantic index
Previously, test discovery used the semantic index as the primary
source and fell back to the syntactic index only for files where the
semantic index was out-of-date. This meant test locations came from the
semantic index, which only records a point position rather than the
full symbol range.

Flip the priority: use syntactic scan results as the primary source
(which have correct location ranges) and supplement with semantic index
results. The semantic results are range-fixed via
'textDocument/documentSymbol' before being returned.

This logic is unified into a single 'combineTests' helper shared by
both 'workspaceTests' and 'documentTests'.

Also fix 'SyntacticSwiftXCTestScanner' to emit extensions as proper
'AnnotatedTestItem' nodes (with 'isExtension: true') rather than a flat
list of methods, so extension test methods are correctly merged into
their class via 'mergingTestsInExtensions'. The class and extension
visitors are unified through a shared 'handleClassOrExtension' helper.

Steffeeen d748f80896 Implement support for textDocument/selectionRange
This enables hierarchical selection expansion in supported editors.

Selection ranges are computed from the AST by walking upward from the
smallest enclosing node to the root. This is implemented by AST nodes
conforming to the `SelectionRangeProvider` protocol. Most nodes use a
default implementation which returns the node's `trimmedRange`.
Other nodes are special-cased to adjust the returned selection ranges
based on other factors.

Alex Hoppen 425e1322a1 Explicitly close the index when shutting down SourceKit-LSP
`IndexStoreDB` moves its index to the `saved` directory when it is deallocated. Because `IndexStoreDB` is primarily owned by `UncheckedIndex`, we rely on deallocating this object to save the index store. This is fairly brittle because various parts of the codebase may hold transient references to that object as reported in https://github.com/swiftlang/sourcekit-lsp/issues/2455#issuecomment-3873561003.

Explicitly remove the reference from `UncheckedIndex` to `IndexStoreDB`. While this still isn’t perfect because other parts of the code base may hold references to `IndexStoreDB` but those should be a lot rarer, resulting in a more consistent closing of the index.

loveucifer 27cf04e2ed Implement textDocument/typeDefinition request (#548)
Add support for the textDocument/typeDefinition LSP request, which
finds the type of the symbol at a given position and returns the
location of that type's definition.

This uses the same type definition lookup mechanism as the inlay hint
resolution feature, which queries cursorInfo for the new type
declaration location fields (typeDeclFilePath/Line/Column) with
fallback to index lookup using typeDeclUsr.

Fixes #548

loveucifer 8e300ee443 add go-to-definition for inlay hints (#2318)
Implements resolveProvider for inlay hints to enable navigating to type
definitions. When an inlay hint showing a type is resolved, the server
looks up the type's definition location using cursorInfo and the index.

- store variable position in InlayHint.data for resolution
- add inlayHintResolve to LanguageService protocol
- implement resolve handler using cursorInfo and index lookup
- enable resolveProvider: true in capabilities
- add test for resolve functionality

Shut down language services when a workspace is closed

- Added shutdownOrphanedLanguageServices to clean up services no longer in use
- When workspace folders are removed, we now shut down their associated language services
- This properly terminates clangd and other language server processes when workspaces close

loveucifer 7437d92453 Fix language services lifecycle management in Workspace
Closes #2209

- Only call `setLanguageServices` from `openDocument` to avoid race conditions
- Remove language services when documents are closed via `removeLanguageServices`
- `SourceKitLSPServer.languageServices` now just returns services without storing them
- Fixed a small typo (serveer -> server) while I was in there

This way the languageServices dictionary only tracks documents that are actually open,
and we avoid race conditions since openDocument is a blocking request for that document.

lijunliang.9819 c40476c191 feat: Fallback to swiftmodule interface when index lookup fails for definition
Currently, `indexBasedDefinition` relies heavily on IndexStoreDB. If a symbol
belongs to a binary framework or a library that hasn't been indexed (but has
module info provided by sourcekitd), the definition request fails or returns
empty results.

This change adds a fallback mechanism in `definitionLocations`. When no
occurrences are found in the index, we check if `systemModule` information
is available on the symbol. If so, we trigger `definitionInInterface` to
generate the textual interface (via `editor.open.interface`) and return that
location.

This improves navigation for binary dependencies (XCFrameworks) and SDKs
partially covered by the index.

loveucifer 70d900e799 Extend copied file mapping to all LSP requests returning locations
This addresses issue #2276 by ensuring that all LSP requests that return source file locations
map copied header files back to their original locations, not just jump-to-definition.

Previously, only the definition request applied this mapping. Now, the following requests
also adjust locations for copied files:
- textDocument/references
- textDocument/implementation
- workspace/symbol
- callHierarchy/prepare
- callHierarchy/incomingCalls
- callHierarchy/outgoingCalls
- typeHierarchy/prepare
- typeHierarchy/supertypes
- typeHierarchy/subtypes

This provides consistent navigation behavior, ensuring users are always taken to the original
source files instead of build artifacts when possible.

Alex Hoppen 219428328c Address my own review comments
Apply the following changes:
- Check for the presence of `#Playgrounds` textually before getting the module name in `SwiftPlaygroundsScanner`. This is important because getting the module name requires us to get build settings for the file, which can be expensive. Do the cheaper check first
- Make `syntacticTests` and `syntacticPlaygrounds` closures capture the workspace instead of passing the workspace from the `SwiftSyntacticIndex` back out. I like this better because now we can’t accidentally pass the wrong workspace to a `SwiftSyntacticIndex`, eg. to `buildTargetsChanges`.
- Capture the initialize result in `TestSourceKitLSPClient` instead of using `postInitialization` to capture the result
- Minor cleanup of unnecessary abstractions, likely artifacts of earlier iterations
- Restructure tests so that every test has its own list of source files, allowing for easier local reasoning – turns out some of these tests didn’t even need to open a workspace, just to check the initialize response
