perf: do not store canonicalized entries in cache

[Boshen]

In monitor-oxc, 14325 / 22568 = 63% of cache entries are canonicalized path.

Can't figure out how though 🤔 .

This is stalled in the paths cache for a single package:

/Users
/Users/boshen/oxc/test-resolver/node_modules/router/index
/Users/boshen/oxc/test-resolver/node_modules/.pnpm/router@2.2.0
/Users/boshen/oxc/test-resolver/node_modules/router/index.js
/Users/boshen/oxc
/
/Users/boshen/oxc/test-resolver/node_modules/.pnpm/router@2.2.0/node_modules/router/index.js
/Users/boshen/oxc/test-resolver/node_modules/router
/Users/boshen/oxc/test-resolver/node_modules/.pnpm/router@2.2.0/node_modules/router
/Users/boshen/oxc/test-resolver/node_modules/.pnpm
/Users/boshen/oxc/test-resolver/node_modules/.pnpm/router@2.2.0/node_modules
/Users/boshen/oxc/test-resolver
/Users/boshen/oxc/test-resolver/node_modules
/Users/boshen

The only information we need to store is

/Users/boshen/oxc/test-resolver/node_modules/router -> /Users/boshen/oxc/test-resolver/node_modules/.pnpm/router@2.2.0

All other saved information is redundant and can be reconstructed on the fly.
