update-version

Use this when a PR contains docs changes with `<AvailableFrom v="...">` and the value should reflect the next release version. 1. Get the canonical version from `main`: ```bash git fetch origin main --quiet git --no-pager show origin/main:packages/core/src/version.ts ``` Read `VERSION` from that file (for example: `4.0.468`), then compute the next patch version by incrementing the patch number by 1 (`4.0.469`). 2. Find `AvailableFrom` entries changed in the current PR: ```bash git --no-pager diff origin/main...HEAD -- packages/docs | rg 'AvailableFrom v="' ``` 3. Update only `AvailableFrom` values touched by this PR so they match the computed next patch version from step 1. 4. Do not change unrelated `AvailableFrom` values outside the PR diff. 5. Commit and push the update.
