fix(delete): publish tombstones to the write relays so deletes propagate

Root cause of "deleted/tombstoned videos still show in the UI": normal video
publishes fan out to the uncapped WRITE relay set, but both delete paths — the
soft-delete tombstone (revertVideo) and the NIP-09 deletion — published only to
this.relays, the CAPPED read set (<=8). A video published broadly was therefore
tombstoned on just a subset; every relay outside that subset kept serving the
original event, so the video resurrected on the next load (the tombstone's
created_at was already bumped strictly-newer, so replacement worked — it just
never reached the relays that mattered).

Add getDeletePublishRelays() (prefer write set, fall back to read set, then
bundled defaults) and use it for both delete publishes, mirroring publishVideo.

Also removed a stray `const a = 1` debug leftover at end of client.js.

Tests: getDeletePublishRelays prefers the write set / falls back to read; and a
call-site test that revertVideo publishes the tombstone to the full 12-relay
write set rather than the 2-relay capped read subset. Mutation-verified —
restoring `this.relays` at the call sites fails the propagation test.

Build + full lint green.
