Release dec 2025 (#15)

* Resolves issue #13

- Switched model to bge-small-en-v1.5
- Added lazy re-embedding
- Added model version tracking per vector
- Added conversion of vectors to the new model

* Add lfs support to the workflow.

* Implements importance scoring with decay + voting #6

* Resolves issue #5 by marking observations as superseeded and scheduled for deletion

* Implement pattern detection #7

* Improve injections and observations accuracy

- Session start: Recent observations for project context (recency-based)
- User prompt: Semantically relevant observations (similarity-based with threshold)

* Added two stage retrieval with bi and cross encoder #8

* Implement query expansion and reformulation #9

* Knowledge graph and relationships ( resolves #4 )

- File Overlap Detection: Detects relationships when observations modify/read the same files
- Concept Overlap Detection: Detects relationships based on shared semantic concepts
- Type Progression Detection: Infers relationships from natural observation type progressions (e.g., discovery → bugfix = "fixes")
- Temporal Proximity Detection: Detects relationships between observations in the same session within 5 minutes
- Narrative Mention Detection: Detects explicit relationship language in narratives (e.g., "fixes", "depends on", "supersedes")

* Add visualisation of the relations to the dashboard.

* fixup! Add visualisation of the relations to the dashboard.

* Update documentation with new settings and screenshots.
