bump: .cfg.toml should not track template-bundles.yml as a bumpversion file in downstream repos

[HarryCampion]

Problem

.rhiza/.cfg.toml includes a [[tool.bumpversion.files]] entry for .rhiza/template-bundles.yml:

[[tool.bumpversion.files]]
filename = ".rhiza/template-bundles.yml"
version_template = "version: {current_version}"
search = "version: {current_version}"
replace = "version: {new_version}"
regex = false
ignore_missing_files = true

template-bundles.yml is a rhiza-go template artefact — it belongs to the template repo itself, not to downstream projects. When a downstream repo syncs .rhiza/.cfg.toml, make bump attempts to rewrite the version string in that file. If the downstream excludes template-bundles.yml from sync (as expected), the bump either silently no-ops (because ignore_missing_files = true) or produces confusing behaviour.

A downstream project had to patch this out manually by removing the stanza from .cfg.toml and excluding the file in template.yml.

Suggestion

Remove the template-bundles.yml bumpversion entry from .cfg.toml in the template. Version tracking for template-bundles.yml should be handled within the template repo itself (e.g. via a separate, template-only bumpversion config or a dedicated make target), not baked into the config that is synced downstream.
