Add incremental re-review on new PR commits (#388)

* add incremental re-review on new PR commits

When new commits are pushed to a PR that Pullfrog has previously reviewed,
automatically perform a focused re-review on only the new changes. Includes
a supersede mechanism to abort stale in-flight reviews on rapid pushes, a
new IncrementalReview mode with incremental diff + prior-feedback awareness,
and a PRReview tracking model so re-review fires for both auto-reviewed and
manually-triggered PRs. Reviews now always submit (APPROVE when clean).

* simplify re-review eligibility and add summary to incremental reviews

Remove the path1/path2 distinction for re-review eligibility — now simply
requires prReReview=enabled and a prior Pullfrog review on the PR. Show
the re-review toggle regardless of prCreated setting. Add a top-level
summary body to incremental reviews for consistency with full reviews.

* consolidate workflow_run completed handling and track completedAt

Removes the duplicate exported handleWorkflowRunCompleted in favor of
the private one, merges status + orphan resolution logic into a single
path, and sets completedAt on both normal completion and orphan cancel.

Made-with: Cursor

* fix rebase conflict resolution: restore eligibility logic, incremental review summaries, and exhaustiveness check

- replace deleted hasPullfrogReviewedPR call with WorkflowRun.findFirst
  (the utility file was removed by the dedup improvements commit)
- restore IncrementalReview summary body in modes.ts and selectMode.ts
  (lost during ca0168b conflict resolution; origin had re-added them via f98f902)
- use switch + satisfies never for workflow_run event dispatch
- lowercase comments per project conventions

Made-with: Cursor

* fix workflow-run polling architecture and improve incremental review prompts

move polling loops from server actions to client to avoid serverless timeouts
(pollForCompleted ran up to 600s in a single invocation). each server action
is now a single DB check; client drives retries. also fix misleading prompt
text about incremental diff scope and remove dead code in handleWebhook.

Made-with: Cursor

* await reportReviewNodeId to eliminate race condition and webhook sleep

- refactor reportReviewNodeId from fire-and-forget to async/awaited,
  guaranteeing the dedup signal lands before the tool returns
- remove the 5-second grace period sleep in the synchronize webhook
  handler (no longer needed with the awaited PATCH)
- update IncrementalReview guidance to use get_review_comments for
  detailed prior line-level feedback instead of just review summaries
- remove dead fallbackUrl field from CheckStartedResult type

Made-with: Cursor

* fix rebase artifacts: broken triggeringIssue reference, review formatting, and prompt wording

IncrementalReview: `### Checklist
1. Checkout the PR via \`${ghPullfrogMcpName}/checkout_pr\` — this returns PR metadata and a \`diffPath\`. Read the diff to identify the major areas of change.
2. Generate the incremental diff using the \`before_sha\` from EVENT DATA: \`git diff <before_sha>...HEAD\`. This isolates only the new commits. If the command fails (e.g., force-push rewrote history), fall back to reviewing the full PR diff.
3. Fetch previous reviews via \`${ghPullfrogMcpName}/list_pull_request_reviews\`. For the most recent Pullfrog review, call \`${ghPullfrogMcpName}/get_review_comments\` with the review ID to retrieve specific prior line-level feedback. Include the prior review summary and comment details when crafting subagent tasks.
4. Delegate multiple subagents in a single \`${ghPullfrogMcpName}/delegate\` call, each focused on a specific area of the new changes. Provide both the full diff path and the incremental diff.
5. After all subagents return, consolidate their findings into a single review.
### Crafting each task
Each task in the \`tasks\` array should include:
- the full diff file path AND the incremental diff (so the subagent can see both new changes and full context)
- what specific area/aspect to focus on
- instruct it to prioritize reviewing code in the incremental diff while using the full diff for context and to catch any changes not covered by the incremental diff
- include the prior review comments (from step 3) so the subagent knows what feedback was already given — instruct it to avoid repeating prior issues and to note whether prior feedback was addressed by the new commits
- instruct it to actively hunt for problems: trace data flow, check boundaries, explore failure modes, verify assumptions, consider lifecycle, spot performance issues
- draft inline comments with NEW line numbers from the full PR diff — every comment must be actionable (2-3 sentences max)
- call \`${ghPullfrogMcpName}/set_output\` with a JSON object: \`{ "summary": "...", "comments": [{ "path": "file.ts", "line": 42, "body": "..." }, ...] }\`
### Post-delegation
After all tasks complete, consolidate into a **single** review:
- merge the \`comments\` arrays from all subagent outputs
- if subagents found actionable issues: submit one \`${ghPullfrogMcpName}/create_pull_request_review\` with \`approved: false\`, the merged comments, and a unified summary body
- if no subagent found actionable issues: submit with \`approved: true\` and a brief positive summary (no inline comments)
- call \`${ghPullfrogMcpName}/report_progress\` with the summary
- if no subagent found actionable issues, skip the review — just call \`report_progress\` noting the PR was reviewed
Use max effort for thorough reviews.`,
