docs: fix README — ASCII art alignment, broken links, deprecated text

- Fix architecture ASCII art box widths to match @ocas/* names
- Remove nonsensical 'legacy alias ocas is deprecated' line
- Fix package links: packages/ocas → packages/core, etc.
- Add full project name: Object Content Addressable Store
- Add License section

+**Object Content Addressable Store** — self-describing CAS with JSON Schema typed nodes.
 
 ## Overview
 
-ocas is a monorepo for storing and validating JSON data in a content-addressable store (CAS). Each node has a typed payload: its `type` field is the hash of a JSON Schema node that describes the payload shape. Hashes are 13-character Crockford Base32 strings derived from XXH64 over deterministic CBOR encoding.
+OCAS is a monorepo for storing and validating JSON data in a content-addressable store (CAS). Each node has a typed payload: its `type` field is the hash of a JSON Schema node that describes the payload shape. Hashes are 13-character Crockford Base32 strings derived from XXH64 over deterministic CBOR encoding.
 
 A bootstrap meta-schema is stored as a self-referencing seed node (`type === hash`). All other schemas are registered as nodes typed by that meta-schema. Payloads can reference other nodes via `format: "cas_ref"` fields; the library provides traversal, reference extraction, and integrity verification.

-Binary: `ocas` (from `@ocas/cli`; legacy alias `ocas` is deprecated). Default store:
-`~/.ocas`. The store is auto-created and bootstrapped on first use — there is
-no `init`/`bootstrap` command, and schemas are ordinary `@schema`-typed nodes (`ocas put
-@schema file.json`), so there is no `schema` subcommand.
