fix: metadata CBOR lookup, save template address, validate freshness (#114)

* fix: deduplicate find_metadata_cbor and pick newest when multiple exist

Stale build artifacts could leave multiple template_metadata.cbor files
in the build output directory, causing "Multiple metadata files found"
errors. Now picks the most recently modified file.

Also deduplicates the function into a single shared copy in publish.rs,
and shows the error reason when metadata is not found in `tari build`.

* feat: save template address after publish, validate metadata freshness

- After `tari publish`, saves the template address to tari.config.toml
  so `tari metadata publish` can omit --template-address
- `tari metadata publish` validates that built CBOR matches Cargo.toml;
  if stale, prompts to rebuild before publishing
- Config file is now created at crate root (Cargo.toml) if CWD is a
  crate, falling back to git root then CWD

* feat: validate metadata freshness in inspect command

tari metadata inspect now checks if the built CBOR matches Cargo.toml
and prompts to rebuild if stale, matching the behaviour already in
tari metadata publish.

* feat: warn when republishing a template with existing address

If tari.config.toml already has a template-address (from a previous
publish), warn the user that republishing an unchanged binary will fail
and a changed binary will get a new address. Defaults to not proceeding.

* feat: prompt to publish metadata after template publish

When metadata is detected after publishing, the user is asked if they
want to publish it to the community server. The prompt is skipped if
--publish-metadata is already set.

* fix: save template_address with snake_case key matching serde expectation

ProjectConfig has no rename_all, so serde expects snake_case field names.
The toml_edit write was using kebab-case which didn't match.
