The compute-hash matrix step intermittently fails on transient `bun install` package resolution errors during `nix build` (e.g. run 26936133588: "error: wrangler@4.50.0 failed to resolve" for ~25 packages on macos-15-intel). Adds a 3-attempt retry loop with linear backoff (10s, 20s) around the build + hash extraction. Success criterion is unchanged (hash extracted from fakeHash mismatch log); structural failures still surface with the full log after the final attempt.
- Replace magic number 3 with MAX_ATTEMPTS variable - Use bash arithmetic for loop

Type of change
What does this PR do?
Wraps
compute-hashin.github/workflows/nix-hashes.ymlwith a 3-attempt retry loop and 10s/20s linear backoff. Successful builds short-circuit on the first attempt; structural failures still surface with the full build log.How did you verify your code works?
YAML syntax check passes. Real flaky runs will exercise the retry once merged.
