Bumps psycopg-c to 3.3.8

Every chat question and AI suggestion request builds the embedding model, and sentence-transformers
checks the Hub for a newer revision each time. With the model already cached that check cost about
2 seconds per request (0.2 seconds without it), and it fails outright when the Hub is unreachable.

Load from the local cache first and only download when the model is missing. A full rebuild still
checks the Hub, so a new model release is picked up together with re-embedding every document
instead of silently mixing revisions.

+# Guidance for AI agents
+
+Read [CONTRIBUTING.md](CONTRIBUTING.md) before working on this repository, especially [Use of AI Tools](CONTRIBUTING.md#use-of-ai-tools). These contribution rules apply to all agent-assisted work.
+
+## Contribution boundaries
+
+- Do not open or submit pull requests, including "on behalf of" a human. The project does not accept PRs from AI agents. Prepare local changes for a human to review, verify, and submit personally.
+- The project does not accept PRs that are entirely or mostly AI-derived. Human submission and disclosure do not override this rule.
+- AI-generated content must be clearly disclosed as described in the contributing guidelines. When handing work back to a human, identify what was generated or changed with AI assistance so they can disclose it accurately.
+- Trust matters. Encourage first-time contributors to discuss their proposed change before preparing a PR, especially for large changes or changes involving AI-generated code. New features and enhancements should almost always target an existing feature request with community interest and discussion.
+- The project prefers thoughtful, well-described ideas to AI-generated pull requests. Help contributors describe their problem, use case, desired behavior, and who would benefit. An implementation is not required for a valuable contribution, and a flawed implementation can obscure a useful idea before it receives proper discussion.
+- AI tools have lowered the effort needed to produce a PR, but reviewing and maintaining it still requires substantial work. Encourage discussion of the idea before investing in implementation and review.
+- Issue reports must describe observed behavior, reproduction steps, and relevant logs. Do not add speculative root causes, code analysis, or proposed fixes to agent-generated reports.
+
+## Security reports
+
+- AI-assisted security reports must meet the legitimacy and verification requirements in [SECURITY.md](SECURITY.md#ai-assisted-submissions). A human must verify a real Paperless-ngx code path, concrete reproduction steps, affected versions, and realistic security impact before submission.
+- Account for existing permission checks, configuration requirements, and trust boundaries. Speculation, scanner output, or concerns about third-party software or deployment choices without a demonstrated Paperless-ngx vulnerability do not meet this threshold and may be closed without extended discussion.
+- Disclose AI assistance and use the private vulnerability reporting channel specified in [SECURITY.md](SECURITY.md#reporting-a-vulnerability).
+
+## Working on changes
+
+- Read the relevant code, tests, and documentation before editing. Paperless-ngx is complex: trace interactions between affected components rather than assuming a change is isolated.
+- Keep changes focused on the requested work and follow existing patterns. Avoid unrelated refactoring, formatting, dependency updates, or generated-file changes.
+- Consider effects on permissions, document processing, background tasks, storage, and the API when those areas are involved.
+- Add or update meaningful tests for behavior changes and regressions. Do not weaken tests or checks to make a change pass.
+- Update user or developer documentation when behavior or setup changes.
+- Keep credentials and private documents out of commits, fixtures, logs, and examples.
+
+## Repository and validation
+
+- `src/`: Django back end.
+- `src-ui/`: Angular front end, managed with `pnpm`.
+- `docs/`: Documentation.
+- `docker/` and `scripts/`: Deployment and development tooling.
+- Base functional changes on `dev`; documentation-only changes may target `main`.
+
+Follow [the development documentation](docs/development.md) for environment setup and testing. Common checks after setup are:
+
+- Back end: run `uv run pytest` from `src/` (use a test path to focus on the affected area).
+- Front end: run `pnpm test` and `pnpm lint` from `src-ui/`.
+- Formatting and other pre-commit checks: run `uv run prek run --files <changed-files>` from the repository root.
+
+When handing work back, summarize the changes, the checks actually run and their results, and any remaining uncertainty. Clearly state when a check could not be run; do not claim verification that did not happen. The human contributor must understand and independently verify the contribution before submitting it.

@@ -4,6 +4,18 @@ If you feel like contributing to the project, please do! Bug fixes and improveme
 
 ⚠️ Please note: Pull requests that implement a new feature or enhancement _should almost always target an existing feature request_ with evidence of community interest and discussion. This is in order to balance the work of implementing and maintaining new features / enhancements. Pull requests that are opened without meeting this requirement may not be merged.
 
+## Trust and collaboration
+
+Paperless-ngx places a high value on trust between contributors and maintainers. If you have not contributed before, consider starting with a discussion before preparing a pull request, especially for a large contribution or one involving AI-generated code.
+
+Paperless-ngx is complex, and understanding how its components interact takes time. A change that appears correct in isolation can have consequences elsewhere in the application. Contributors should understand the code they submit, explain how it fits into the project, and work with maintainers through review. Starting with smaller, focused contributions can help build that understanding and trust.
+
+We prefer thoughtful, well-described ideas to AI-generated pull requests. You do not need to supply an implementation for your contribution to be valuable. Explain the problem you have encountered, your use case, the behavior you would like to see, and who would benefit. Concrete examples, alternatives you have considered, and relevant constraints help the community discuss and refine the idea.
+
+AI tools have lowered the effort needed to produce a pull request, but evaluating one still requires substantial maintainer time. Maintainers still need to establish whether the implementation is correct, fits the project, and can be maintained over time.
+
+A flawed implementation can also obscure a good idea: discussion becomes focused on problems with the generated code before the community has considered whether the underlying proposal is useful. Starting with the idea gives it a fair discussion on its own merits and lets contributors and maintainers agree on an approach before investing in implementation and review.

 If you want to implement something big:

Only `rebuild` checks the Hub for a newer revision of the model, so a model update is picked up together with re-embedding every document.
