chore: gitignore tsbuildinfo files

[jlia0]

Description

Add *.tsbuildinfo to .gitignore. These are TypeScript incremental build cache files generated by tsc --build and should not be tracked in version control.

Changes

• Add *.tsbuildinfo pattern to .gitignore

Testing

• Verified build still works with npm run build

Greptile Summary

This PR adds *.tsbuildinfo to .gitignore to prevent TypeScript incremental build cache files from being tracked in version control — a correct and reasonable housekeeping change. However, it is incomplete: 6 .tsbuildinfo files are already tracked by git across the packages/ directory, and simply adding a .gitignore pattern does not untrack them. Those files will continue to be committed and show up in diffs until git rm --cached is run for each of them.

Key changes:

• Adds *.tsbuildinfo pattern under the # TypeScript build output section in .gitignore

Issues found:

• Pre-existing tracked *.tsbuildinfo files (packages/channels, packages/core, packages/main, packages/server, packages/teams, packages/visualizer) need to be explicitly removed from the git index via git rm --cached in a follow-up commit for this change to be fully effective.

Confidence Score: 3/5

• Safe to merge as-is, but the intent of the change won't be fully realized without also untracking already-committed .tsbuildinfo files.
• The .gitignore change itself is correct and harmless, but it is incomplete — 6 .tsbuildinfo files remain tracked in the git index, meaning they will still be committed on future changes. The PR needs a git rm --cached step to fully accomplish its stated goal.
• .gitignore — the pattern is correct but the pre-existing tracked files must be removed from the index separately.

Already-tracked .tsbuildinfo files won't be ignored

Adding *.tsbuildinfo to .gitignore only prevents future untracked files from being committed. However, there are currently 6 .tsbuildinfo files already tracked by git in this repository:

• packages/channels/tsconfig.tsbuildinfo
• packages/core/tsconfig.tsbuildinfo
• packages/main/tsconfig.tsbuildinfo
• packages/server/tsconfig.tsbuildinfo
• packages/teams/tsconfig.tsbuildinfo
• packages/visualizer/tsconfig.tsbuildinfo

These files will continue to be tracked and show up in diffs even after this change. To fully untrack them, the following command needs to be run and the result committed:

git rm --cached packages/channels/tsconfig.tsbuildinfo \
               packages/core/tsconfig.tsbuildinfo \
               packages/main/tsconfig.tsbuildinfo \
               packages/server/tsconfig.tsbuildinfo \
               packages/teams/tsconfig.tsbuildinfo \
               packages/visualizer/tsconfig.tsbuildinfo

Or more concisely:

git rm --cached **/*.tsbuildinfo
