fix: restore release index publication

The v0.10.2 native packages completed, but the publication job rejected the valid --base-url option before any GitHub Release or mirror assets were published. Normalize CLI option names and cover the exact workflow arguments with a regression test.

Advance recovery metadata to 0.10.3 and move the approved user-facing notes forward, removing the unpublished 0.10.2 note to avoid a duplicate first-open display.

Release note: 0.10.3 carries forward the approved mirror-node and conversation timestamp improvements from the unpublished 0.10.2 candidate.
