v0.3.6 — LLM answers, graph visualization, command handbook

What's new

LLM answers in the CLI

fittok query now streams an LLM answer by default — no flags needed:

```bash
uvx fittok query "how does auth work" # streams answer
uvx fittok query "how does auth work" --code # raw relevant code
uvx fittok query "how does auth work" --budget 1500 # cap slice size
```

Set one key and it just works:

• `ANTHROPIC_API_KEY` → claude-haiku-4-5 (recommended)
• `OPENAI_API_KEY` → gpt-4o-mini (fallback)

No key? fittok falls back to `--code` and prints a setup hint.

Interactive code graph

```bash
uvx fittok graph # full graph in browser
uvx fittok graph --query "auth" # highlight relevant nodes green
```
Requires: `uv pip install "fittok[ui]"`

Savings footer on by default

`FITTOK_SHOW_SAVINGS` now defaults to `true` — every MCP answer includes a `🪙 saved X%` footer. Set to `false` to disable.

Command handbook

Full Oracle-style reference for every subcommand, flag, env var, and exit code: docs/HANDBOOK.md

Upgrade

```bash
uv cache clean fittok # clears cached version, next uvx run pulls 0.3.6
```
