docs: rename to coyote-bundle-template and document the bundle lifecycle

Adds the identity manifest and rewrites the README around the current
install surface: --install with owner/repo shorthand and --git-host,
provenance-backed --list-bundles / --update-bundle / --uninstall, and
the update semantics for files and mcp entries.

+## Managing the installed bundle
+
+Coyote records everything a bundle install writes (file paths, MCP server
+entries, and content hashes) in a provenance store, which powers the full
+lifecycle:
+
+```sh
+coyote --list-bundles                          # name, version, source, drift
+coyote --install <bundle-name>                 # update by installed name
+coyote --update-bundle <bundle-name>           # update from the recorded source
+coyote --update-bundle <bundle-name>#<ref>     # move a pin while updating
+coyote --update-bundle <bundle-name> --yes     # non-interactive: keep local edits, refresh the rest
+coyote --uninstall <bundle-name>               # remove owned files and MCP entries
+coyote --uninstall <bundle-name> --yes         # skip the confirmation prompt
+```
+
+The same operations are available in the REPL as `.list bundles`,
+`.install <bundle-name>`, and `.uninstall <bundle-name> [--yes]`.
+
+Updates and uninstalls never clobber your local edits: files you modified
+after install are prompted for (and kept by default on uninstall), while
+untouched files refresh or delete silently. See the
+[Sharing Configurations wiki](https://github.com/Dark-Alex-17/coyote/wiki/Sharing-Configurations)
+for the full ownership and drift model.
+
+## The manifest (`coyote-bundle.yaml`)
+
+The optional manifest at the repo root declares the bundle's identity, and
+nothing else. Coyote discovers installable content by scanning the asset
+directories; the manifest never lists files.
+
+```yaml
+name: coyote-bundle-template
+version: "1.0.0"
+description: Starter template for Coyote bundles
+homepage: https://github.com/Dark-Alex-17/coyote-bundle-template
+```
+
+- `name` is how consumers refer to the bundle in `--update-bundle` and
+  `--uninstall`. Ship a manifest so your bundle keeps a stable name across
+  forks; without one, Coyote derives the name from the repository name.
+- `version` shows up in `--list-bundles` (falls back to the short commit SHA).
+- If your chosen name collides with another installed bundle or a built-in
+  asset category, Coyote qualifies it with the repo owner (`owner/name`)
+  instead of overwriting anything.
+
 ## Layout
 
-Coyote only reads these top-level directories. Anything else in the repo is
