docs: add 10-year schedule and clarify Alpha as nightly builds

 - Add comprehensive 10-year schedule table (v27-v36) with Alpha, Release, LTS, and End of Life dates
 - Clarify that Alpha channel uses only nightly builds (no formal alpha releases, reducing releaser workload)
 - Link to nodejs.org/download/nightly for early testing
 - Reorder Timeline section: v26 → v27 → 10-year table

 ### About the Alpha Channel
 
-The Alpha channel replaces odd-numbered releases.
+The Alpha channel replaces odd-numbered releases. During this period, only [nightly builds](https://nodejs.org/download/nightly/) are available for early testing.
 
 **Who it's for:** Library authors and CI pipelines testing compatibility with upcoming breaking changes. Not intended for production use.
 
 **What to expect:**
 - Semver-major changes land during this phase
 - No security patches (only stable releases receive security fixes)
-- API may change between Alpha releases
-- ABI stability guarantees are still being defined and will be documented separately
+- API may change between builds
 
 **Why:** Provides early feedback on breaking changes without maintaining another full release line. Also allows landing V8 updates earlier in the cycle, so we don't ship a single V8 version per year.
