fix: handle unencoded spaces in catalog paths and prevent NPE on miss…

[alaurie]

Summary of Changes

This PR fixes a workflow failure (URISyntaxException) caused by repositories containing unencoded spaces in their file paths (e.g., .../Apache Camel/...), and addresses several edge cases around GitHub content fetching and JSON deserialization.

Changes Made

• Safe Download Handling: Replaced the direct GHContent.read() invocation with a two-tier approach:
  1. Sanitizes spaces (%20) in getDownloadUrl() and opens the stream directly via URI.create().
  2. Falls back to ghContent.getOwner().getFileContent(...) if direct streaming fails.
• URI Error Handling: Added IllegalArgumentException to the main loop's catch block to prevent unhandled URI parser exceptions from crashing the catalog aggregation run.
• NPE Prevention in Deserialization: Added explicit null checks for aliases and templates entries after Gson deserialization, preventing crashes on catalog files that omit either block.
• GitHub Search Syntax: Fixed search extension filter from .extension(".json") to .extension("json").
• Search Resiliency: Wrapped PagedSearchIterable paging in fetchCatalogsWithRetry() to catch generic exceptions alongside GHException.

Verification

• Script now successfully iterates through search results containing paths with spaces without crashing.
• Empty or partial catalog files parse cleanly without throwing NullPointerException.

Just realised I ran the Palantir formatter on it when I saved in Intellij so its moved a bunch of stuff around. That ok, or want to do it with how it was? @maxandersen

@maxandersen fixed the formatting issue up now. Tested locally again and still works.
