Proposed changes

• add a new pdf exporter under pkg/reporting/exporters/pdf that implements the existing reporting Exporter interface
• include report sections for summary + severity counts + findings overview + per-finding details
• include optional raw request/response blocks with bounded truncation and omit-raw support
• make exporter safe for concurrent Export calls by guarding shared state and snapshotting before render
• wire PDF exporter into reporting configuration (yaml: pdf) and exporter registration in pkg/reporting/reporting.go
• add focused unit tests for constructor behavior, nil event handling, omit-raw behavior, truncation, and concurrency

Proof

Executed locally:

go test ./pkg/reporting/exporters/pdf
go test -race ./pkg/reporting/exporters/pdf
