97b065596d feat: wire permission checker into engine tool execution 
Tools now go through permission.Checker before executing:
- plan mode: denies all writes (fs.write, bash), allows reads
- bypass mode: allows all (deny rules still enforced)
- default mode: prompts user (pipe: stdin prompt, TUI: auto-approve for now)
- accept_edits: auto-allows file ops, prompts for bash
- deny mode: denies all without allow rules

CLI flags: --permission <mode>, --incognito
Pipe mode: console Y/N prompt on stderr
TUI mode: auto-approve (proper overlay TODO)

Verified: plan mode correctly blocks fs.write, model sees error.

6c70a2ceaf fix: TUI overflow, scrollable header, tool output, git branch 
- Fixed: chat content no longer overflows past allocated height.
  Lines are measured for physical width and hard-truncated to
  exactly the chat area height. Input + status bar always visible.
- Header scrolls with chat (not pinned), only input/status fixed
- Git branch in status bar (green, via git rev-parse)
- Alt screen mode — terminal scrollback disabled
- Mouse wheel + PgUp/PgDown scroll within TUI
- New EventToolResult: tool output as dimmed indented block
- Separator lines above/below input, no status bar backgrounds

b9faa30ea8 feat: add router foundation with task classification and arm selection 
internal/router/ — core routing layer:
- Task classification: 10 types (boilerplate, generation, refactor,
  review, unit_test, planning, orchestration, security_review, debug,
  explain) with keyword heuristics and complexity scoring
- Arm registry: provider+model pairs with capabilities and cost
- Limit pools: shared resource budgets with scarcity multipliers,
  optimistic reservation, use-it-or-lose-it discounting
- Heuristic selector: score = (quality × value) / effective_cost
  Prefers tools, thinking for planning, penalizes small models on
  complex tasks
- Router: Select() picks best feasible arm, ForceArm() for CLI override

Engine now routes through router.Select() when configured.
Wired into CLI — arm registered per --provider/--model flags.

20 router tests. 173 tests total across 13 packages.

33dec722b8 feat: add security firewall with secret scanning and incognito mode 
internal/security/ — core security layer baked into gnoma:
- Secret scanner: gitleaks-derived regex patterns (Anthropic, OpenAI,
  AWS, GitHub, GitLab, Slack, Stripe, private keys, DB URLs, generic
  secrets) + Shannon entropy detection for unknown formats
- Redactor: replaces matched secrets with [REDACTED], merges
  overlapping ranges, preserves surrounding context
- Unicode sanitizer: NFKC normalization, strips Cf/Co categories,
  tag characters (ASCII smuggling), zero-width chars, RTL overrides
- Incognito mode: suppresses persistence, learning, content logging
- Firewall: wraps engine, scans outgoing messages + system prompt +
  tool results before they reach the provider

Wired into engine and CLI. 21 security tests.

f0633d8ac6 feat: complete M1 — core engine with Mistral provider 
Mistral provider adapter with streaming, tool calls (single-chunk
pattern), stop reason inference, model listing, capabilities, and
JSON output support.

Tool system: bash (7 security checks, shell alias harvesting for
bash/zsh/fish), file ops (read, write, edit, glob, grep, ls).
Alias harvesting collects 300+ aliases from user's shell config.

Engine agentic loop: stream → tool execution → re-query → until
done. Tool gating on model capabilities. Max turns safety limit.

CLI pipe mode: echo "prompt" | gnoma streams response to stdout.
Flags: --provider, --model, --system, --api-key, --max-turns,
--verbose, --version.

Provider interface expanded: Models(), DefaultModel(), Capabilities
(ToolUse, JSONOutput, Vision, Thinking, ContextWindow, MaxOutput),
ResponseFormat with JSON schema support.

Live verified: text streaming + tool calling with devstral-small.
117 tests across 8 packages, 10MB binary.
