Merge apex-types repository into outline-parser

[nawforce]

Summary

This PR merges the apex-types repository (v1.3.0) into outline-parser to simplify the dependency chain and enable future improvements to diagnostic position reporting.

Changes

Added Files (25 total)

• 18 Scala files - Core type definitions from com.financialforce.types
  • Type interfaces: ITypeDeclaration, IMethodDeclaration, IFieldDeclaration, IConstructorDeclaration, etc.
  • Base types: Modifier, Annotation, Location, TypeRef, QualifiedName, etc.
• 3 Scala files - JS platform-specific API (io.github.apexdevtools.api)
• 4 Java files - JVM platform-specific API and SPI (io.github.apexdevtools.api + io.github.apexdevtools.spi)

Modified Files

• build.sbt: Removed apex-types dependency
• README.md: Added note about bundled type definitions

Testing

✅ All 6,302 existing tests pass successfully

• JVM tests: ✅ Passed
• JS tests: ✅ Passed (RPC cleanup error is known/benign)

Benefits

1. Simplified dependency chain: Reduces from 3 repos (apex-types → outline-parser → apex-ls) to 2 repos
2. Enables position fixes: Can now add location fields to Modifier and Annotation without cross-repo coordination
3. Faster iteration: Changes to type definitions and parser can be tested together
4. Reduced maintenance: One less repo to maintain, one less version to coordinate

Migration Path for Consumers

Before (outline-parser 1.x):

libraryDependencies ++= Seq(
  "io.github.apex-dev-tools" %%% "apex-types" % "1.3.0",
  "io.github.apex-dev-tools" %%% "outline-parser" % "1.2.1"
)

After (outline-parser 2.0.0):

libraryDependencies ++= Seq(
  "io.github.apex-dev-tools" %%% "outline-parser" % "2.0.0"
)

Import paths remain unchanged (com.financialforce.types.*), so no code changes needed in consumers.
