chore: Enhance developer tooling and documentation

Adds `actionlint` to the pre-commit configuration to validate GitHub Actions workflows. Significantly expands the `AGENTS.md` file with a comprehensive summary of new features and changes in Go 1.24 and 1.25, along with actionable recommendations for the project. Additionally, normalizes markdown list formatting across various documentation files for consistency.

 # Agent Guidelines for articulate-parser

 ## Build/Test Commands
+
 - **Build**: `task build` or `go build -o bin/articulate-parser main.go`
 - **Run tests**: `task test` or `go test -race -timeout 5m ./...`
 - **Run single test**: `go test -v -race -run ^TestName$ ./path/to/package`
@ -14,43 +15,413 @@
 ## Code Style Guidelines

 ### Imports
+
 - Use `goimports` with local prefix: `github.com/kjanat/articulate-parser`
 - Order: stdlib, external, internal packages
 - Group related imports together

 ### Formatting
+
 - Use `gofmt -s` (simplify) and `gofumpt` with extra rules
 - Function length: max 100 lines, 50 statements
 - Cyclomatic complexity: max 15
 - Cognitive complexity: max 20

 ### Types & Naming
+
 - Use interface-based design (see `internal/interfaces/`)
 - Export types/functions with clear godoc comments ending with period
 - Use descriptive names: `ArticulateParser`, `MarkdownExporter`
 - Receiver names: short (1-2 chars), consistent per type

 ### Error Handling
+
 - Always wrap errors with context: `fmt.Errorf("operation failed: %w", err)`
 - Use `%w` verb for error wrapping to preserve error chain
 - Check all error returns (enforced by `errcheck`)
 - Document error handling rationale in defer blocks when ignoring close errors

 ### Comments
+
 - All exported types/functions require godoc comments
 - End sentences with periods (`godot` linter enforced)
 - Mark known issues with TODO/FIXME/HACK/BUG/XXX

 ### Security
+
 - Use `#nosec` with justification for deliberate security exceptions (G304 for CLI file paths, G306 for export file permissions)
 - Run `gosec` and `govulncheck` for security audits

 ### Testing
+
 - Enable race detection: `-race` flag
 - Use table-driven tests where applicable
 - Mark test helpers with `t.Helper()`
 - Benchmarks in `*_bench_test.go`, examples in `*_example_test.go`

 ### Dependencies
+
 - Minimal external dependencies (currently: go-docx, golang.org/x/net, golang.org/x/text)
 - Run `task deps:tidy` after adding/removing dependencies

+## Go 1.24 & 1.25 New Features Reference
+
+This project uses Go 1.24+. Below is a comprehensive summary of new features and changes in Go 1.24 and 1.25 that may be relevant for development and maintenance.
+
+### Go 1.24 Major Changes (Released February 2025)
+
+#### Language Features
+
+**Generic Type Aliases**
+
+- Type aliases can now be parameterized with type parameters
+- Example: `type List[T any] = []T`
+- Can be disabled via `GOEXPERIMENT=noaliastypeparams` (removed in 1.25)
+
+#### Tooling Enhancements
+
+**Module Tool Dependencies**
+
+- New `tool` directive in go.mod tracks executable dependencies
+- Use `go get -tool <package>` to add tool dependencies
+- Use `go install tool` and `go get tool` to manage them
+- Eliminates need for blank imports in `tools.go` files
+
+**Build Output Formatting**
+
+- Both `go build` and `go test` support `-json` flag for structured JSON output
+- New action types distinguish build output from test results
+
+**Authentication**
+
+- New `GOAUTH` environment variable provides flexible authentication for private modules
+
+**Automatic Version Tracking**
+
+- `go build` automatically sets main module version in binaries based on VCS tags
+- Adds `+dirty` suffix for uncommitted changes
+
+**Cgo Performance Improvements**
+
+- New `#cgo noescape` annotation: Prevents escape analysis overhead for C function calls
+- New `#cgo nocallback` annotation: Indicates C function won't call back to Go
+
+**Toolchain Tracing**
+
+- `GODEBUG=toolchaintrace=1` enables tracing of toolchain selection
+
+#### Runtime & Performance
+
+**Performance Improvements**
+
+- **2-3% CPU overhead reduction** across benchmark suites
+- New Swiss Tables-based map implementation (faster lookups)
+  - Disable via `GOEXPERIMENT=noswissmap`
+- More efficient small object allocation
+- Redesigned runtime-internal mutexes
+  - Disable via `GOEXPERIMENT=nospinbitmutex`
+
+#### Compiler & Linker
+
+**Method Receiver Restrictions**
+
+- Methods on cgo-generated types now prevented (both directly and through aliases)
+
+**Build IDs**
+
+- Linkers generate GNU build IDs (ELF) and UUIDs (macOS) by default
+- Disable via `-B none` flag
+
+#### Standard Library Additions
+

+
+### Actionable Recommendations for This Project
+
+#### Immediate Opportunities
+
+1. **Replace `sync.WaitGroup` patterns with `WaitGroup.Go()`** (Go 1.25)
+
+   ```go
+   // Old pattern
+   wg.Add(1)
+   go func() {
+       defer wg.Done()
+       // work
+   }()
+   
+   // New pattern (Go 1.25)
+   wg.Go(func() {
+       // work
+   })
+   ```
+
+2. **Use `testing.B.Loop()` in benchmarks** (Go 1.24)
+
+   ```go
+   // Old pattern
+   for i := 0; i < b.N; i++ {
+       // benchmark code
+   }
+   
+   // New pattern (Go 1.24)
+   for b.Loop() {
+       // benchmark code
+   }
+   ```
+
+3. **Consider `os.Root` for file operations** (Go 1.24)
+   - Prevents path traversal vulnerabilities
+   - Safer for user-provided file paths
+
+4. **Enable Green Tea GC for testing** (Go 1.25)
+   - Test with `GOEXPERIMENT=greenteagc`
+   - May reduce GC overhead by 10-40%
+
+5. **Leverage container-aware GOMAXPROCS** (Go 1.25)
+   - No changes needed; automatic in containers
+   - Improves resource utilization
+
+6. **Review floating-point operations** (Go 1.25)
+   - AMD64 v3+ uses FMA instructions
+   - May change floating-point results (within spec)
+
+7. **Watch nil pointer checks** (Go 1.25)
+   - Compiler bug fix may expose latent nil pointer bugs
+   - Review crash reports carefully
+
+#### Future Considerations
+
+1. **Evaluate `encoding/json/v2`** when stable
+   - Better performance for JSON operations
+   - Currently experimental in Go 1.25
+
+2. **Adopt tool directives** in go.mod
+   - Cleaner dependency management for build tools
+   - Remove `tools.go` if present
+
+3. **Enable FIPS mode if required**
+   - Use `GOFIPS140=1` for compliance
+   - Performance improvements in Go 1.25 (4x faster signing)
+
+4. **Use `runtime/trace.FlightRecorder`** for production debugging
+   - Capture traces of rare events
+   - Minimal overhead when not triggered
