feat(api): add configurable CORS origins via CORS_ORIGINS (#767) 
Replace hardcoded `allow_origins=["*"]` with a parsed `CORS_ORIGINS`
environment variable (comma-separated). Default remains `*` for
backward compatibility — no existing deployment breaks — but the API
now logs a startup warning prompting users to set it explicitly for
production.

Exception handlers now route their CORS headers through a shared
`_cors_headers()` helper that mirrors Starlette's CORSMiddleware
behavior: reflects the request Origin when allowed (handling the
browser-rejected `*` + credentials combination correctly), and omits
`Access-Control-Allow-Origin` for disallowed origins so error bodies
don't leak cross-origin when `CORS_ORIGINS` is configured.

Closes #585, #730.

Based on the original work by Greg Grace in #597; rewritten on top of
current main to address prior review feedback (load_dotenv kept at
top, `import os` grouped with stdlib, `_cors_headers` defined before
its exception-handler callers, origins parsed once at module load)
and to choose a non-breaking default paired with a startup warning
instead of a stricter-by-default origin.

# Changelog
All notable changes to this project will be documented in this file.
The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.1.0/),
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).
## [Unreleased]
### Added
- `OPEN_NOTEBOOK_EMBEDDING_BATCH_SIZE` environment variable to override the embedding batch size; default remains `50`. Helps with CPU-only local embedding and stricter OpenAI-compatible endpoints (#735)
- `CORS_ORIGINS` environment variable to configure the API's allowed origins (comma-separated). Default remains `*` for backward compatibility; the API now logs a startup warning prompting users to set it for production deployments. Exception responses honor the configured origins when explicitly set (#585, #597, #730)
## [1.8.5] - 2026-04-14
### Changed
- Embedding chunking is now token-based instead of character-based, improving chunk sizing consistency for CJK and mixed-language content (#542, #749)
- `OPEN_NOTEBOOK_CHUNK_SIZE` and `OPEN_NOTEBOOK_CHUNK_OVERLAP` semantics changed from characters to tokens; default reduced from 1200 characters to 400 tokens to stay safely below the 512-token ceiling of BERT-family embedders (e.g. mxbai-embed-large) after accounting for tokenizer mismatch and splitter overshoot. Existing stored embeddings are unaffected; only new ingestions use the new chunking.
### Fixed
- Credentials endpoint no longer crashes (500) when encryption key doesn't match stored credentials (#740)
- Broken credentials are now shown with a decryption warning and can still be deleted
- DELETE endpoint for broken credentials supports model migration (`migrate_to` parameter)
## [1.8.4] - 2026-04-09
### Security
- Fix Remote Code Execution (RCE) via Jinja2 Server-Side Template Injection in transformations (CVSS 9.2 Critical)
- Fix arbitrary file write via path traversal in file upload (CVSS 7.0 High)
- Fix arbitrary file read via Local File Inclusion in source creation (CVSS 8.2 High)
### Dependencies
- Bump ai-prompter to >=0.4.0 (uses Jinja2 SandboxedEnvironment to prevent SSTI)
## [1.8.3] - 2026-04-07
### Security
- Fix SurrealDB injection via unsanitized `order_by` query parameter in `GET /api/notebooks` (CVSS 8.7 High)
- Add allowlist validation for sorting parameters in notebooks endpoint
- Replace f-string query interpolation with parameterized `$variable` binding in source chat and migration queries
- Add defensive validation in `get_all()` base method to prevent injection via `order_by` parameter
## [1.8.2] - 2026-04-06

- DashScope (Qwen) and MiniMax provider support via Esperanto v2.20.0 (#725)

- 413 errors now classified with user-friendly message in error classifier
- Misleading "Created 0 embedded chunks" log in `process_source_command` — embedding is fire-and-forget, so the count was always 0; now logs "embedding submitted" instead
