docs: examples for every hard requirement + mort migration blueprint

Phase 7: nine runnable examples/ programs (parse, failover chains with
trailing alias, tiers, LLM_* env providers, multimodal, tool loop,
Generate[T], agent, skills); docs/mort-migration.md mapping mort's
go-llm/go-agentkit usage onto majordomo APIs with the planned additive
library extensions and conversion order; README finalized with the
complete matrix.

+# Examples
+
+One runnable program per hard requirement. Each takes `-model` (a full
+majordomo spec — single target, chain, or alias) and reads provider keys
+from the environment (`OLLAMA_API_KEY`, `OPENAI_API_KEY`,
+`ANTHROPIC_API_KEY`, `GOOGLE_API_KEY`, `LLM_*` DSNs).
+
+| Example | Shows |
+|---|---|
+| `parse/` | resolving a spec and a plain chat |
+| `failover/` | failover chains, incl. the trailing-alias form, + health behavior |
+| `tiers/` | registering custom tiers (aliases) and parsing them |
+| `envproviders/` | `LLM_*` env-DSN providers (foreman) as first-class chain elements |
+| `multimodal/` | attaching an image; capability-aware normalization |
+| `tools/` | the canonical tool-call loop against the raw Model API |
+| `structured/` | typed structured output via `Generate[T]` |
+| `agent/` | an agent with a toolbox running the tool-dispatch loop |
+| `skillexample/` | attaching the ready-made clock + calc skills to an agent |
+| `live/` | the Phase 8 live-validation harness (real Ollama Cloud; needs `.env`) |
+
+Run any of them like:
+
+```bash
+OLLAMA_API_KEY=... go run ./examples/parse -model "ollama-cloud/minimax-m3:cloud"
+```
