Description

Describe the bug When running the analyze --full command, the tool fails to recognize translation key usage if keys are accessed through intermediate variables.

To Reproduce

  1. Access a translation key with chained access (works fine):

    context.t.section.subsection.key

  2. Assign intermediate variables:

    final tSection = context.t.section;
final tSub = tSection.subsection;

    Then use:

    tSub.key

  3. The analyze --full command incorrectly marks the key as unused.

Expected behavior Keys accessed via intermediate variables are not detected and are incorrectly flagged as unused.

Contributor guide

Research direction
Inspect the `analyze` command's logic for resolving translation keys. Focus on variable assignment and chained access handling. The bug likely occurs because the analyzer only tracks direct chained access patterns (e.g., `context.t.section.subsection.key`) and misses indirect access via intermediate variables. Examine the AST traversal and symbol resolution to ensure intermediate assignments are followed.
