Jake Hillion b9a78f6f3a ci: compute CURRENT_PROJECT_VERSION from semver
Previous Sparkle builds were cut from a different repo with different
build numbers, breaking version ordering. Users aren't receiving updates
because CFBundleVersion values don't reflect the actual version sequence.

Added a step to compute the build version deterministically from semver:
PRERELEASE + (1000 * PATCH) + (1_000_000 * MINOR) + (1_000_000_000 * MAJOR).
Release versions use prerelease=999 to ensure they're always higher than
their prereleases (e.g., 1.0.61 > 1.0.61-alpha.3).

This ensures consistent version ordering across repos, allowing Sparkle
to correctly identify and deliver updates to users.

Test plan:
- Verified formula with test script:

```sh
compute_version() {
  VERSION="$1"
  BASE_VERSION="${VERSION%%-*}"
  MAJOR=$(echo "$BASE_VERSION" | cut -d. -f1)
  MINOR=$(echo "$BASE_VERSION" | cut -d. -f2)
  PATCH=$(echo "$BASE_VERSION" | cut -d. -f3)

  if [[ "$VERSION" == *-* ]]; then
    PRERELEASE_PART="${VERSION#*-}"
    PRERELEASE_NUM="${PRERELEASE_PART##*.}"
    if ! [[ "$PRERELEASE_NUM" =~ ^[0-9]+$ ]]; then
      PRERELEASE_NUM=0
    fi
  else
    PRERELEASE_NUM=999
  fi

  BUILD_VERSION=$((PRERELEASE_NUM + 1000 * PATCH + 1000000 * MINOR + 1000000000 * MAJOR))
  printf "%-20s -> %12s\n" "$VERSION" "$BUILD_VERSION"
}

compute_version "1.0.61-alpha.2"
compute_version "1.0.61-alpha.3"
compute_version "1.0.61"
compute_version "1.0.62-alpha.1"
compute_version "1.1.0-alpha.1"
compute_version "2.0.0-alpha.1"
compute_version "0.0.0-alpha.0"
compute_version "0.0.1-alpha.1"
compute_version "1.2.3"
compute_version "1.2.3-beta.5"
```

- Output:

```sh
Version              -> Build Number
----------------------------------------
1.0.61-alpha.2       ->   1000061002
1.0.61-alpha.3       ->   1000061003
1.0.61               ->   1000061999
1.0.62-alpha.1       ->   1000062001
1.1.0-alpha.1        ->   1001000001
2.0.0-alpha.1        ->   2000000001
0.0.0-alpha.0        ->            0
0.0.1-alpha.1        ->         1001
1.2.3                ->   1002003999
1.2.3-beta.5         ->   1002003005
```

- Confirmed ordering: alpha.2 < alpha.3 < release < next-alpha
