mvalentsev c4baceccb4 docs: fix stale milla-jovovich org URLs in website and plugin manifests (#787 )

Follow-up to #766 which covers version.py, pyproject.toml, README,
CHANGELOG, and CONTRIBUTING. These 11 files still had the old org
name in URLs:

- website/ (VitePress config + 6 docs pages)
- .claude-plugin/ (plugin.json repository, README marketplace command)
- .codex-plugin/ (plugin.json URLs, README links)

Author name fields are intentionally unchanged.

Core storage and retrieval run locally on ChromaDB and SQLite. Optional reranking features can add an API dependency.

Verbatim Retrieval First

MemPalace starts from a simple premise: store the source text and retrieve it well. The benchmarked raw mode does not require an LLM extraction step.

System	LongMemEval R@5	API Required	Cost
MemPalace (hybrid)	100%	Optional	Free
Supermemory ASMR	~99%	Yes	—
MemPalace (raw)	96.6%	None	Free
Mastra	94.87%	Yes	API costs
Mem0	~85%	Yes	$19–249/mo

The raw 96.6% LongMemEval result is the baseline story: strong recall without requiring an API key or an LLM in the retrieval pipeline.
