6c21d69 doc: add txospenderindex release note (Lőrinc)
1ced471 index: shrink txospenderindex value markers (Lőrinc)

Pull request description:

  **Problem:** `TxoSpenderIndex` values are never read: `FindSpender()` only uses the key, which already encodes the spender's disk position, but the values are written as single-byte `\0`(instead of empty values).

  **Fix:** Write zero-byte markers for new `txospenderindex` entries instead.
  Existing indexes stay readable because both formats use the same keys and the value is ignored.
  Rebuilding is only needed to shrink old entries.

  **Related work:** This complements #35568, which saves another ~4.5 GB by dropping bloom filters.
  A #35531-style rewrite could let existing indexes reclaim both savings without a full rebuild.

  **Reproducer:** Automated tests weren't added, but the manual reproducer below builds both commits, checks old/new format compatibility through `gettxspendingprevout`, and prints rebuilt index sizes.
  On my mainnet datadir this PR shrank `txospenderindex` by ~3.4 GB (from 89G to 86G).
