* Preserve interpolation source text and canonical metadata
Source-only checkpoint; candidate validation and the existing annotation expectation reconciliation remain pending.

* Align existing annotation expectations with CPython metadata
Update only the nine existing expected strings confirmed against pinned CPython 3.15, with explicit user approval.

* Preserve template metadata through compilation and interactive input
Escape literal debug prefixes, retain None AST expression metadata internally, and continue incomplete triple-quoted t-strings in the existing shell.

* Classify normalized unclosed brackets as REPL line continuations

* Nest equivalent REPL parse-error alternatives for Clippy

* Remove fulfilled annotation migration lint workaround
The canonical expected strings no longer trigger literal_string_with_formatting_args, so the previous lint expectation is obsolete.

* Complete lazy-import exception and traceback library closure
Copy canonical traceback and legacy exception mappings with preserved RustPython guards. Copy explicit non-Python library assets by exact path so exception hierarchy data does not expand into the entire test package.

* Provide Python 3.15 traceback metadata for missing modules and attributes
Preserve AttributeError context for missing class attribute deletion, matching type_update_dict. Expose canonical generated missing-stdlib messages through the native sysconfig modules without importing CPython build-specific disabled-module assumptions.
