Description

GCSF populates the file tree at mount time, making O(tree depth) requests to Drive (one request for each level). This can be reduced to O(1) but requires a better strategy for constructing the tree internally.

Research direction
Investigate the current tree construction strategy used during mount time (likely in src/ directory). Review the comments in this issue for prior discussion on potential strategies. Propose a design that builds the tree with O(1) requests, possibly using a flat map and deferred lookups.
