fix(chat): forbid fake tool calls in tool-less (Just chat) mode

REPRODUCED: in the non-agentic path (Tools off / 'Just chat'), asking for
tool-work makes the model role-play tool use — it emits a fake ```json {...}```
'tool call' and says 'let me search/query/pull your sessions' while NOTHING
runs. Reads as a broken/lying app. (The agentic path is fine: verified it
calls search_memory and reports honestly.)

Root cause: build_system_prompt (handle_chat, the tool-less path) never told
the model it has no tools this turn, so it fabricated.

Fix: add a NO-TOOLS directive to the non-agentic system prompt — never emit
tool calls / JSON tool blocks / 'let me pull...' narration; answer from context
only; if a tool is truly needed, say so in one sentence and tell the user to
turn Tools on. Applied to chat.el (source) AND dist/soul.c (the curated TU the
CI compiles), so the CI-built binary carries it.

Verified the FABRICATION repro on the live local soul; could not verify the
patched binary locally (no matching el-runtime version on this machine — a
hand-link against origin/main runtime 404s on all routes). Builds correctly via
CI, which links soul.c against the pinned runtime.
