dimitar aee63bf321 feat: phase 5 — AI agent integration (OpenAI, Ollama, Anthropic)
Add the AI layer that turns scan results into suggested next actions.

Provider model (internal/ai):
- Provider interface with Name() and Suggest(ctx, ScanResult) returning
  []Suggestion (repo_path, action, message, command, priority 0-2)
- NewProvider factory resolves the configured provider and enforces that
  cloud providers have their API key in the configured env var; Ollama
  needs no key
- OpenAIProvider: Chat Completions with response_format json_object
- OllamaProvider: local /api/chat with format:json for structured output
- AnthropicProvider: Messages API with system prompt and key/version
  headers; all three fall back to provider-appropriate defaults for
  base_url and model
- Shared client: 60s timeout, 4 MiB response cap, JSON encode/decode,
  HTTP error surfaces the upstream status and body

Prompt design (BuildPrompt):
- Renders the full repository status table (name/status/branch/ahead/
  behind/changes) plus strict output rules: exact suggestion schema,
  allowed actions, smallest-safe-step guidance, no invented repositories,
  return [] when healthy

Parsing (parseSuggestions):
- Tolerates ```json fences and surrounding prose, clamps priorities to
  0-2, caps the result, and rejects replies without a JSON array

Suggestion display (presenter.Suggestions):
- "AI SUGGESTIONS" table (repository/action/priority/message/command)
  rendered below the scan table with priority color-coded (red/yellow/
  green); empty results say all repositories are healthy

Guarded execution (--ai-execute, experimental):
- RunConfirmed executes a suggestion's command inside its repository only
  after explicit per-command y/N confirmation, and only for actions on an
  allowlist (commit/push/pull/stash/checkout) so LLM output can never run
  arbitrary shell commands; cancellation aborts remaining suggestions

CLI wiring:
- scan: AI block after the table when --ai is set and format is not json
  (JSON streams stay machine-readable); failures degrade to warnings
- watch: AI is queried only on the first frame and when something changed
  since the previous frame, to avoid hammering the provider every interval
- New --ai-execute flag and provider validation in config (openai/ollama/
  anthropic), included in the config dump

Testing:
- httptest-based provider tests verifying request shape (model, auth
  headers, path), response parsing, API error bodies, HTTP failures, and
  cancellation
- Parse tests: plain/fenced/prose replies, empty arrays, garbage,
  truncated JSON, priority clamping
- Execution tests: unsafe actions and empty commands never run, declined
  confirmations are skipped, confirmed commands execute in the repo dir,
  failing commands surface errors
- Presenter suggestion table and empty-state tests

Verified: go build, go vet, go test -race, gofmt clean; end-to-end smoke
test against a local fake Ollama server (request shape confirmed, table +
suggestions rendered) and the missing-API-key warning path.
