chore(sync): bring zdeploy/ZHelpers up to the private tree, sanitized (#64)
The mirror's deploy pair had drifted ~280 lines behind: it lacked the
transactional .env preserve/restore (an interrupted deploy could destroy
server-side env files), the stderr-flattening step wrapper (a successful
deploy reported failure and skipped its own verification), and the
verification rework (channel re-picked every retry, edge only with a Host
to route by, verify.timeoutSeconds, honest split of "stale build" vs "no
channel answered").

The sync is byte-faithful to the private tree except where the mirror's
own Sanitization suite demands otherwise - and it caught the first copy:
three failures for private project names, a private domain, and a
private-only script name that rode along in comments. Each war story keeps
its lesson and loses its cast, per the convention already in the file
("EvoCivilCode: deploy/" was already published as "(deploy/, infra/,
...)"). That suite going red on an unsanitized copy is exactly what it
exists for.

Also in this change:

- tests/VerifyPlan.Tests.ps1 - the channel-selection rules are pure
  functions and Pester pins them (no domain => no edge attempt; the PS 5.1
  one-element-unroll trap). First verification tests in the mirror.
- README: the verify block now documents viaProxy/upstream (they shipped
  in the docker-network read but were never in the README),
  timeoutSeconds, and the channel order with why it re-resolves per retry.
- README.txt: generated plain-text twin, via scripts/readme_txt.py
  (vendored from the fleet's reference implementation; the file is
  generated, never edited by hand).
- CHANGELOG.md/.txt: entries merged into the existing Unreleased sections.

CHECKSUMS.txt refreshed (42 entries). Pester: 240 passed, 0 failed.
Both synced files parse clean.

Observed, untouched: the Unreleased section carries duplicate "### Fixed"
headings from earlier appends; folding them risks reordering entries whose
prose references their neighbours, so it is left for the next release cut
(zbump #110 rolls Unreleased into the version being cut).

"""Render README.md to README.txt with the markdown markup removed.
README.txt exists for terminals, pagers and anywhere markdown doesn't
render. It is generated - never edit it by hand:
python scripts/readme_txt.py # rewrite README.txt
python scripts/readme_txt.py --check # exit 1 if it is out of sync
The test suite runs --check, so a README.md edit that forgets to
regenerate fails CI rather than shipping a stale mirror.
