chore(core): add parseAnalytics function for debugging

[mrgrain]

Reason for this change

It always bothered me that we don't have an easy way of converting a template analytics string back for debugging.
This PR adds a debugging utility to decode analytics strings back into readable ConstructInfo objects.

Description of changes

• Added parseAnalytics() function that reverses the formatAnalytics() encoding
• Added parsePrefixEncodedList() helper to decode the trie structure
• Added trieToConstructInfos() to convert trie back to ConstructInfo array
• Added comprehensive tests verifying parseAnalytics is the inverse of formatAnalytics

The implementation handles the v2:deflate64 format by base64 decoding, gunzipping, and parsing the prefix-encoded trie structure.

Describe any new or updated permissions being added

None

Description of how you validated changes

Added unit tests covering:

• Single construct parsing
• Multiple constructs with same version
• Nested module constructs
• Different versions

All tests verify that parseAnalytics(formatAnalytics(x)) === x
