docs: document macros as first-class custom commands

Covers top-level .name invocation, the new description/isolated macro
fields (with the non-isolation persistence, fail-fast, nested-macro, and
.exit caveats), workspace .coyote/macros/ + --no-workspace-macros,
enabled_macros scoping at global/role/agent/session levels, and
.macro enable|disable across the README and every example config.
graph.example.yaml gains a note that enabled_macros is ignored in graph
configs.

CHANGELOG intentionally untouched: it is generated by commitizen at
release time from the conventional commit subjects.

Implements plans/custom-commands-design.md §8.

+* [Macros](https://github.com/Dark-Alex-17/coyote/wiki/Macros): Automate repetitive tasks and workflows with Coyote "scripts" (macros). Macros are Coyote's custom commands: invoke any macro directly by name (e.g. `.review main`), with tab-completion, right alongside the built-in REPL commands.
+    * Give a macro a `description` (shown in `.list macros` and completions) and set `isolated: false` to run its steps on the live session, exactly as if you typed them. Note that non-isolated steps are recorded in the session, and mutating steps (`.role`, `.model`, ...) persist after the macro ends — by design. Steps are fail-fast: an error aborts the remaining steps, but completed steps' effects remain. A non-isolated macro step cannot invoke another macro, and a `.exit` step never exits the REPL.
+    * Commit project-specific macros to `.coyote/macros/` in your repo — they shadow same-named global macros (opt out with `--no-workspace-macros`).
+    * Scope which macros are invocable with `enabled_macros` in the global config, a role, an agent, or a session (most specific wins; an empty list disables all macros), and toggle at runtime with `.macro enable|disable <name>`.
