Set executable bit on installed binary

[ChiragAgg5k]

Summary

brew install appwrite/appwrite/appwrite fails on 19.2.0 with:

```
brew: exec failed (EACCES): /opt/homebrew/Cellar/appwrite/19.2.0/bin/appwrite
Error: ... `appwrite completion bash` exited with 1
```

Root cause

The four release artifacts on https://github.com/appwrite/sdk-for-cli/releases/tag/19.2.0 are uploaded with 0644:

```
$ ls -l /tmp/appwrite-cli-*
-rw-r--r-- /tmp/appwrite-cli-darwin-arm64
-rw-r--r-- /tmp/appwrite-cli-darwin-x64
-rw-r--r-- /tmp/appwrite-cli-linux-arm64
-rw-r--r-- /tmp/appwrite-cli-linux-x64
```

bin.install preserves the source permissions, so the rename to bin/appwrite carries the missing +x. As soon as anything tries to exec it — currently generate_completions_from_executable inside def install — Homebrew aborts.

Fix

Defensively chmod 0755 after the install branch. This unblocks installs today regardless of the perms shipped in the release artifact.

Follow-up

The upload step in the sdk-for-cli publish workflow should also chmod +x each binary before uploading so future releases are correct at the source. Tracking that separately.

Test plan

• Local: brew uninstall appwrite && brew install appwrite/appwrite/appwrite — installs cleanly and shell completions register
• CI: test-bot must pass on macos-latest and ubuntu-latest

Greptile Summary

This PR adds a single chmod 0755 call after the binary install step to defensively ensure the executable bit is always set on bin/appwrite, working around upstream release artifacts being uploaded with 0644 permissions. The fix correctly covers both the build.head? and stable-release install branches, and uses Ruby's proper octal literal syntax.

Confidence Score: 5/5

Safe to merge — minimal, well-scoped fix with no logical or security concerns.

The change is two lines that defensively chmod the installed binary. It correctly targets both install branches, uses proper Ruby octal syntax, and directly addresses the documented EACCES failure. No edge cases or regressions are introduced.

No files require special attention.

Important Files Changed

Filename	Overview
Formula/appwrite.rb	Adds chmod 0755 on the installed binary after both install branches to fix EACCES on exec when upstream artifacts are uploaded with 0644 permissions.
