fix(github): reuse review instructions across native turns (#16971)

## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - GitHub events continue an ordinary task and can reuse its provider conversation. > - Each automatic event appended the full review policy and PR description. > - Native GitHub follow-ups also repeated task history because only Slack used the compact path. > - This pull request separates admitted review configuration from commit updates. > - A verified resume sends the current messages and changed configuration. A fresh session gets full context. > - This reduces repeated input while retaining review rules and current tool checks. ## Linked Issues or Issue Description Refs #13959, #16645, #16901. **What happened?** Opening a PR and pushing twice stored three full review prompts. A later native turn repeated all three in a retained provider conversation. **Expected behavior** A new event supplies its commit and event data. The harness delivers stable review instructions once per retained conversation and configuration. Fresh sessions receive full instructions. **Steps to reproduce** 1. Enable automatic GitHub reviews for a repository. 2. Open a PR, let the review finish, and push two new commits. 3. Inspect task messages and the native submitted envelopes. Before this fix, the policy and old requests repeat. ## What Changed - Store compact automatic event messages. Fetch the PR description through the existing metadata tool when needed. - Load review instructions from processed deliveries bound to the company, task, agent, and source comments. Preserve each admitted policy snapshot. - Use the existing verified native continuation path for complete GitHub text batches. Deliver configuration changes using a key over endpoint, PR conversation, revision, and instructions. - Keep full bootstrap input for fresh sessions and failed resume, including board follow-ups with no new GitHub event. Retain existing framing for incomplete batches, attachments, interactions, and recovery. - Keep the same configuration identity across automatic review, discussion, and automatic review. Coalesced requests use the last accepted request's admitted policy. - Add regression and database coverage. Update the execution contract and verification recipe. ## Verification - Red: the new event-size regression failed because policy and PR body repeated. The GitHub continuation regression failed because it returned no compact prompt. - Green: focused policy, continuation, native input, and adapter prompt tests passed (231 tests). Native resume/fresh-bootstrap cases passed (9 tests). - The signed-webhook/database case passed at `6296168253`. It checks configuration edits, queued older snapshots, coalesced policy selection, discussion continuity, board follow-ups, and company/task/agent/comment boundaries. The private PostgreSQL template used 12 connections because the host reached its semaphore limit with the default settings. - The earlier broad channel/session integration run passed 1,432 tests. Later review fixes invalidated that run. The latest focused database case passed after those fixes. - Reviewer regressions failed against the previous lookup, then passed with the fix: a mixed-revision batch delivered multiple policies, and a discussion lost the configuration identity. The board wake-to-rendered-prompt regression also failed before repair. - `pnpm -r typecheck`, `pnpm build`, `node scripts/check-maps.mjs`, and `git diff --check` passed on the final source. - Full local `pnpm test:run` exposed follow-up/fixture failures during development. Those cases are fixed and pass separately. The stale run was stopped after source edits. Full-suite validation for the final commit passed in CI. - All required CI checks passed for `6296168253`, including tests, typechecks, build, and clean public npm install checks. The two unrelated Storybook checks were skipped. - A live two-turn Codex smoke could not start: the local macOS sandbox helper rejected execution of the installed Codex 0.153.4 binary. No live GitHub/provider acceptance or deployment is claimed. ## Risks Skipping instructions is safe only after a verified checkpoint resume with the correct previous run. The full bootstrap remains available if resume fails. Changed or previously unknown configuration is sent again. Tests cover these cases. Tool authorization and publication checks still run under the current server policy. No database migration is required. ## Model Used OpenAI GPT-6 through Codex, with tool use and code execution. The exact deployment model identifier and context window are not exposed in this session. No delegated agents were used. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented any risks above - [x] All Paperclip CI gates are green - [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge --------- Co-authored-by: Paperclip <noreply@paperclip.ing>

+Automatic GitHub review messages contain the current event and commit identifiers,

+Configuration identity includes the endpoint, PR conversation, revision, and rendered
