Add a Limitations section to the README and a docs/RELEASE-NOTES-0.1.0.md release asset, both re-derived from current shipped behavior rather than assumed.

The caveats are the deliberate deferrals, verified against the binary and source: diff is working-tree-vs-current-check-in and name-status only, with no rev-to-rev form; the sync server code is a fixed informational placeholder while the per-repo project code is real (derived on init, persisted, adopted on clone); the R and W cards are parsed but not interpreted, whereas T and U are acted on; and stash/grep/ui/settings have no equivalent.

The notes name the local fossil 2.28 that the interop smoke passes against, flag that the runner version lags and must be confirmed at ship, and cite the pack re-deltification measurements to their benchmark commit bab9303056. check-in: ab4951c2e8 user: dmestas tags: p5b-docs
