* feat: return matching scores from jev
Replace the experimental three-argument Boolean function with jev(text, prompt) returning a Float64 probability in [0, 1]. Move threshold comparisons into SQL and update tests and migration examples.
Signed-off-by: Lei, HUANG <ratuthomm@gmail.com>
* feat: add Jev choice and score functions
Share asynchronous execution across Noul, Choice, and Score. Validate JSON criteria before requests and return typed scalar answers. Add SQL and HTTP mock coverage with usage examples.
Signed-off-by: Lei, HUANG <ratuthomm@gmail.com>
* refactor: use generic AI SQL function names
Expose ai_match, ai_choose, and ai_score and move their implementation, tests, and usage guide under generic AI names. Document the current unreleased interface without migration history.

* fix: share constant AI criteria within each batch
Borrow scalar string arguments and lazily parse constant criteria once per batch. Share the parsed allocation across requests while preserving NULL propagation and batch validation before HTTP calls.

* feat: preserve AI score uncertainty in JSONB results
Return score, confidence, and probabilities in criteria-level order from one evaluation. Validate the distribution and preserve provider precision. Add JSON extraction, uncertainty, and single-request regressions, and document confidence-aware ranking.

* docs: explain reuse of volatile AI evaluations
Document repeated SELECT and WHERE evaluation costs as N + M requests, and show subquery aliases for reusing scalar or structured AI results without additional model calls.

Run the existing registry regression without the jev feature in both PR tests and merge-queue coverage, alongside the existing feature-enabled test runs.

Document the per-expression/batch concurrency bound and track process-wide limiting, rate-limit backoff, and request budgets and metrics as stabilization prerequisites.

* feat: enable renamed ai-functions feature by default
Rename the Jev Cargo feature across the command, query, and function crates and enable it in their defaults. Update CI and documentation, retaining an isolated no-default-features registry check and the runtime API opt-in.
Signed-off-by: Lei, HUANG <ratuthomm@gmail.com>
* ci: remove extra AI feature-off checks
Use the regular AI-enabled unit and coverage runs for the default feature configuration. Keep feature-off validation available locally and update the usage guide to match.

* feat/gdump:
### Add Support for Jemalloc Gdump Flag
- **`jemalloc.rs`**: Introduced `PROF_GDUMP` constant and added functions `set_gdump_active` and `is_gdump_active` to manage the gdump flag.
- **`error.rs`**: Added error handling for reading and updating the jemalloc gdump flag with `ReadGdump` and `UpdateGdump` errors.
- **`lib.rs`**: Exposed `is_gdump_active` and `set_gdump_active` functions for non-Windows platforms.
- **`http.rs`**: Added HTTP routes for checking and toggling the jemalloc gdump flag status.
- **`mem_prof.rs`**: Implemented handlers `gdump_toggle_handler` and `gdump_status_handler` for managing gdump flag via HTTP requests.
