Add alert discovery in sweep, investigation workflow, and post-action routing (bump PR for non-affected, private fork for affected). Closes #4
Repos can opt in via `investigate.dismiss_not_affected: true` in their .blender/blender.yml. When enabled, BLEnder dismisses Dependabot alerts as "inaccurate" instead of opening bump PRs for non-affected packages. Every investigation now posts a row to a tracking issue on the target repo. The issue is created on the first run, then reused. Each row is a comment (not a body edit) to avoid races when many workflows run concurrently.

Replace tracking issue with JSON artifact to avoid exposing alert details on public repos. Remove open_bump_pr (no file changes made it useless). Rename "not affected" to "unaffected" everywhere. Extract shared sanitize_for_prompt into scripts/sanitize.sh. Fix "dedup" jargon in sweep.py comments.

Replace JSON artifact with a styled HTML report. The report shows alert metadata, verdict, and source code snippets for each vulnerable path identified during investigation. Styled like a coverage report for easy in-browser review.

Move read_code_snippet, render_html, and write_summary out of post_alert_action.py into a dedicated module. Keeps the action script focused on orchestration.
zizmor flagged workflow-level actions:write as overly broad. Only the investigate job needs it for upload-artifact.
