chore: remove extensionless MAINTAINERS duplicate

[hyperpolymath]

Removes the extensionless MAINTAINERS, superseded by MAINTAINERS.adoc.

This isn't only a duplicate — the removed file was wrong. It carried:

• no SPDX header
• maintainership attributed to "Metadatastician / @metadatastician"

while MAINTAINERS.adoc carries the CC-BY-SA-4.0 header and correctly names Jonathan D.A. Jewell as Lead Maintainer. It is scaffold boilerplate — byte-identical across 37 of 40 repos that had it, the other 3 trivial variants.

Owner-directed 2026-08-26. Raised as a PR because this repo's ruleset requires pull requests and verified signatures, which a direct API commit cannot satisfy.

Poem

A rabbit checks the empty file,
Then hops along the leafy mile.
No maintainer notes remain,
The burrow rests without a chain.
The branch is clean, the work is done.
