fix: Add symlink setting (opt-in) to fix workflows relying on them

[jeroenev]

What does this PR do?

This PR adds a setting to allow RG / Grep to follow symlinks, like it used to do.
A setting was added to make this behavior opt-in, to avoid issues with complex folder structures + symlinks

How did you verify your code works?

Ran the tests, and tested with codebases where modules are added via symlinks, which PR #11415 broke.
That PR disabled following symlinks in search tools, to fix performance issues from symlinks to large directories or symlink loops.
By doing so it breaks other workflows that rely on symlinks to add modules, so this setting fixes that.

Fixes#10365

Note that this just adds a setting for reverting to the original behavior from 2 weeks ago, as it was changed in PR #11415

Am running version opencode 1.2.18 on Fedora. The @ does not detect the symlink in the workspace, but if I explicitly ask the agent "what do you see" in the folder symlink, it is able to list out the content in it.

Nice work @jeroenev . Perhaps solve the merge conflict, so the anomaly team can merge this PR.

( I am not part of anomaly or anyhing, just like to have this fixed as well 🙃 )

[jeroenev]

Rebased and fixed all conflicts, I hope this can get merged soon.
but yeah it can take a while until someone looks at this PR
they're probably getting overloaded 🙃
there are so many changes this PR gets conflicts every week, but I'm happy to keep rebasing until someone looks at it to merge
