v1.9.0: Newer isn’t always more correct

Two weeks ago, @jim_jeffers left a comment that became the core of v1.9.0:

A recent note shouldn’t automatically overwrite an older decision.

He was right.

Second Brain now supports:

Canonical: trusted decisions, facts, preferences
Draft: tentative thoughts
Deprecated: outdated memories kept for records, but removed from recall

So if yesterday’s random note conflicts with a six-month-old product decision, Second Brain protects the trusted memory instead of clobbering it.

We also added episodic vs semantic memory for cleaner recall:

Episodic: what happened
Semantic: what you know

Huge thanks to @jim_jeffers, @anand_thakkar1, and everyone who pushed on memory quality during launch.
