feat: add smartcase and globless path searches

[CyanVoxel]

Summary

This PR adds "smartcase" style path searches and allows for non-glob searches to still return results. Smartcase searches will act as case-insensitive when the entire query is lowercase, but will turn case-sensitive if one or more capital letters are present in the query. Meanwhile the glob detection is now based on whether or not a query starts or ends with a "*" character.

This PR also limits the number of results in the path autocomplete list to 100 items to avoid sluggish search typing that scales with the size of the library.

path: temp

• Returns all paths that have "temp" (Case insensitive) somewhere in the name.
