feat: rate limit pools, elf tree view, permission prompts, dep updates

Rate limits:
- Add PoolRPS/PoolTPM/PoolTokensMonth/PoolCostMonth pool kinds
- Provider defaults for Mistral/Anthropic/OpenAI/Google (tier-aware)
- Config override via [rate_limits.<provider>] TOML section
- Pools auto-attached to arms on registration

Elf tree view (CC-style):
- Structured elf.Progress type replaces flat string channel
- Tree with ├─/└─ branches, per-elf stats (tool uses, tokens)
- Live activity updates: tool calls, "generating… (N chars)"
- Completed elfs stay in tree with "Done (duration)" until turn ends
- Suppress raw elf output from chat (tree + LLM summary instead)
- Remove background elf mode (wait: false) — always wait
- Truncate elf results to 2000 chars for parent context
- Parallel hint in system prompt and tool description

Permission prompts:
- Show actual command in prompt: "bash wants to execute: find . -name '*.go'"
- Compact hint in separator bar: "⚠ bash: find . | wc -l [y/n]"
- PermReqMsg carries tool name + args

Other:
- Fix /model not updating status bar (session.Local.SetModel)
- Add make targets: run, check, install
- Update deps: BurntSushi/toml v1.6.0, chroma v2.23.1, x/text v0.35.0, cloud.google.com/go v0.123.0
