fix: store versions per-repo to prevent fork collisions#17
Merged
Conversation
Previously, versions like 'nightly' from different repos (e.g.,
foundry-rs/foundry vs tempoxyz/tempo-foundry) would overwrite each
other since they were stored under the same directory.
Now versions are stored under `versions/{owner}/{repo}/{version}`,
so each fork has its own isolated version storage.
The list output now shows the repo alongside the version:
`foundryup: foundry-rs/foundry nightly`
Fixes #9 (comment 3666667993)
On startup, foundryup now detects legacy version directories (those stored directly under versions/ without a repo prefix) and automatically migrates them to the new structure under foundry-rs/foundry/. This ensures backwards compatibility for users upgrading from older versions of foundryup.
