address review: move CLI reference to workflow-util, inline in prompt

- Move generateCliReference() to @uncaged/workflow-util
- buildRolePrompt inlines CLI reference directly (no agent tool call)
- Fix Role terminology to use new field names
- Add maintenance comment in cli-reference.ts
- Fix test assertions

-## CAS Commands
-
-\`\`\`
-uwf cas get <hash>                # read a CAS node (type + payload)
-            [--timestamp]         # include timestamp in output
-uwf cas put <type-hash> <data>    # store a node, print its hash
-                                  # <data>: JSON file path or inline JSON string

-uwf cas walk <hash>               # recursive traversal from a node
-uwf cas reindex                   # rebuild type index from all CAS nodes
-uwf cas schema list               # list all registered schemas
-uwf cas schema get <hash>         # show a schema by its type hash

-## Global Options
-
-\`\`\`
-uwf --format <fmt>                # output format: json (default) or yaml
-uwf -V, --version                 # print version

-## Key Concepts
-
-- **Workflow**: YAML definition with roles, conditions, and a routing graph; stored as a CAS node identified by its XXH64 hash.
-- **Thread**: A single workflow execution (ULID). State is an immutable CAS chain; active threads are indexed in \`threads.yaml\`.
-- **Step**: One moderator→agent→extract cycle. Run \`uwf thread step\` repeatedly until \`$END\`.
-- **CAS**: Content-Addressed Storage — all nodes are immutable and identified by hash.
-- **Role**: Named actor with a system prompt and JSON Schema output; the moderator routes between roles.
