feat: remove deprecated functions for v1.13.0 release

[erraggy]

Summary

This PR removes all deprecated package-level convenience functions and prepares the codebase for the v1.13.0 release. It also splits large test files and adds a local code review workflow.

Breaking Changes

Removed Functions (11 total)

parser package:

• Parse(specPath, resolveRefs, validateStructure) → Use ParseWithOptions(WithFilePath(...), ...)
• ParseReader(reader, resolveRefs, validateStructure) → Use ParseWithOptions(WithReader(...), ...)
• ParseBytes(data, resolveRefs, validateStructure) → Use ParseWithOptions(WithBytes(...), ...)

validator package:

• Validate(specPath, includeWarnings, strictMode) → Use ValidateWithOptions(WithFilePath(...), ...)
• ValidateParsed(parseResult, includeWarnings, strictMode) → Use ValidateWithOptions(WithParsed(...), ...)

converter package:

• Convert(specPath, targetVersion) → Use ConvertWithOptions(WithFilePath(...), WithTargetVersion(...))
• ConvertParsed(parseResult, targetVersion) → Use ConvertWithOptions(WithParsed(...), WithTargetVersion(...))

joiner package:

• Join(specPaths, config) → Use JoinWithOptions(WithFilePaths(...), WithConfig(...))
• JoinParsed(parsedDocs, config) → Use JoinWithOptions(WithParsedDocs(...), WithConfig(...))

differ package:

• Diff(sourcePath, targetPath) → Use DiffWithOptions(WithSourceFilePath(...), WithTargetFilePath(...))
• DiffParsed(source, target) → Use DiffWithOptions(WithSourceParsed(...), WithTargetParsed(...))

Migration Impact

• Struct-based API unchanged: New().Method() patterns remain fully supported
• Migration guide provided: See MIGRATION_V1.12_TO_V1.13.md
• All tests passing: 1,547 tests pass with maintained coverage
• Lines removed: ~1,565 lines (deprecated code + tests)

Rationale for v1.13.0 (Minor) instead of v2.0.0 (Major)

While this is technically a breaking change, we're releasing as v1.13.0 instead of v2.0.0 because:

1. The module is still relatively new with minimal library adoption
2. The deprecated functions were clearly marked in previous releases
3. The migration path is straightforward and well-documented
4. The struct-based API (recommended for most use cases) remains unchanged

See CLAUDE.md for the full rationale. Future breaking changes will follow semantic versioning more strictly.

Test File Improvements

Split parser/parser_test.go (2,495 lines) into 6 focused files:

• parser_test.go (456 lines, 15 tests) - Core parsing
• parser_options_test.go (343 lines, 23 tests) - Functional options API
• parser_refs_test.go (340 lines, 5 tests) - Reference resolution
• parser_validation_test.go (524 lines, 7 tests) - Validation
• parser_url_test.go (524 lines, 8 tests) - URL operations
• parser_utils_test.go (338 lines, 5 tests) - Utilities

Benefits: Better organization, maintainability, and avoids token limits for AI tools.

Local Code Review Workflow

Added local code review workflow as replacement for GitHub Actions:

New scripts:

• scripts/local-code-review.sh - Manual code review using Claude Code CLI
• scripts/pre-push-hook - Git pre-push hook for automated review
• scripts/install-git-hooks.sh - One-time setup installer

Benefits:

• Faster feedback (local vs GitHub Actions)
• No GitHub Actions usage/costs for code review
• Immediate feedback during development
• Can review at different stages (uncommitted/staged/branch)

Usage:

# One-time setup
./scripts/install-git-hooks.sh

# Manual review
./scripts/local-code-review.sh branch

# Skip review for specific push
SKIP_REVIEW=1 git push

Test Plan

• All tests pass (1,547 tests)
• make check passes (linting, formatting, tests)
• Code coverage maintained
• Parser tests split successfully (all 63 tests pass)
• Git hooks install and run correctly
• Migration guide updated and accurate

Checklist

• Tests pass
• Code formatted (go fmt)
• Linting passes
• Documentation updated
• Migration guide provided
• Breaking changes clearly documented
