feat(remote): support .dockerignore when copying files to remote host

[cathaysia]

Support .dockerignore files when copying project and mounted volumes to remote container data volumes.

Changes

• Add docker_ignore module for .dockerignore parsing and pattern matching based on the glob crate:
  • Supports comments (#), blank lines, and UTF-8 BOM.
  • Supports negation / exception rules (!) in sequential order.
  • Supports directory-only patterns (/ suffix).
  • Matches root-relative and recursive (**) patterns using glob::MatchOptions { require_literal_separator: true, .. } following Docker / Moby patternmatcher specifications.
  • Respects parent directory exclusion hierarchy (excluding a parent directory prunes children).
• Integrate .dockerignore filtering into directory copying (copy_dir_with_rel and copy_files_filtered) in remote.rs, skipping ignored files and directories during traversal.
• Integrate .dockerignore filtering into Fingerprint scanning so persistent volume incremental sync respects ignore rules.
• Add comprehensive unit tests covering parsing, pattern matching, exception rules, directory copying, and fingerprint scanning.

Hi, could someone please review this?

I think this is fine, some minor nits. One thing this makes me consider is if we should just switch to use ignore which is based on walkdir to traverse the mount

Considering that most of the traversal work involves pruning, using walkedir may not be as beneficial as we thought. I changed the recursion to iteration to avoid potential stack overflow issues.

Is there anything else here that needs to be modified?

[Emilgardis]

No, just need to have a look at the changes once more and then can merge :)
