Resolve relative base paths before joining.

When base is relative, anchor it to env::current_dir() before joining utf8_parent. Otherwise, workspace.root remains relative, and Dir::open_ambient_dir resolves it against the process current directory. Add a test with Some(Path::new(".")) that asserts workspace.root.is_absolute().

only still-valid issues, skip the rest with a brief reason, keep changes
minimal, and validate.

In `@src/manifest/workspace.rs` around lines 25 - 30, Update the workspace root
resolution around the anchor construction to convert a relative Some(base) path
into an absolute path anchored at env::current_dir() before joining utf8_parent,
while preserving absolute base paths and the existing error context. Add
coverage for Some(Path::new(".")) asserting workspace.root.is_absolute().

P1 Badge Record the base-directory seam in the architecture docs

This introduces a new injection seam, but the commit does not update any architecture, design, or developer documentation to define its ownership, permitted call sites, and composition rules. The inline statement that it is “for tests” does not establish whether production callers may reuse it or how it relates to the repository's existing environment-seam taxonomy; document that policy in the appropriate indexed guide as required.
