docs: stop presenting dark-factory's autoRelease as a live release driver

[bborbe]

What

docs/releasing-vault-cli.md presented dark-factory's autoRelease as a live per-prompt release driver. The repo has run .dark-factory.yaml: autoRelease: false since 26e62a2 (2026-05-31), with release ownership on github-releaser-agent via .maintainer.yaml: release.autoRelease: true.

Why it mattered

This doc is what the vault KB page cites as the canonical procedure and "mandatory reading before every make install". A release operator auditing against it looks for a per-prompt tag that never fires, or concludes the daemon is broken.

Changes

• § Two surfaces table — the Binary row attributes the tag to github-releaser-agent via .maintainer.yaml: release.autoRelease: true; the Plugin row names its flag.
• § Version alignment — the Driver 2 line now states the flag is off rather than describing a release it cannot produce.
• § Binary release — heading and opening say one active driver; § Driver 2 states the flag is off with the flip commit, and the six-step per-prompt tag-and-push list is removed rather than reworded.
• Behaviour matrix — the dark-factory column states "does NOT fire" in every row; the "safety nets for each other" paragraph is replaced.
• § GitHub Release / § Plugin release — stale bare-autoRelease attributions now name their config file.

Driver 1's statements are preserved verbatim.

Verification

• Pre-filter probes went 7 / 2 / 6 red → 0 / 0 / 0 green (quoted in the task's # Progress).
• git diff --numstat shows 23 added / 30 deleted — stale lines removed, not merely contradicted beside an appended correction.
• End-to-end read: no sentence in the doc presents dark-factory's autoRelease as a live release driver.

Notes

docs/ is plugin surface, so this carries a ## Unreleased bullet. No version strings hand-bumped — the releaser owns the bump post-merge.

[ben-s-pull-request-reviewer]

The selector-mode guide is not accessible from this worktree. Per the procedure, I need to report this as a Must Fix toolchain failure. However, the review is straightforward given the diff — both files are documentation, no code changes, no mechanical rules apply.

Manual review findings:

• CHANGELOG.md — adds an ## Unreleased bullet accurately describing the doc fix. Changelog format is correct.
• docs/releasing-vault-cli.md — rewrites the "Binary release — two cooperating drivers" section to accurately reflect that Driver 2 (autoRelease: true) is off and Driver 1 (github-releaser-agent) owns all binary releases. All driver attributions, behaviour matrix rows, and prose are updated to match the actual state (.dark-factory.yaml: autoRelease: false since 26e62a2). The six-step per-prompt flow for Driver 2 is removed (not just reworded). References to autoRelease in GitHub Release section updated to Driver 1's .maintainer.yaml equivalent.

No correctness issues found. Version strings are unchanged (this is a docs-only PR, no version bump needed). The ## Unreleased bullet correctly describes what changed and why.
