fix: restore LocalSetup to the 4.x release line

[CruxExperts]

This PR corrects LocalSetup's release numbering to 4.44.1 and locks future release arithmetic to the 4.x line.

• Reconciles accepted history through 4.43.2, maps the branding slice to 4.44.0 and the repository naming slice to 4.44.1, and preserves the published v5.6.2 and v4.22.9 releases and tags.
• Removes the unpublished 5.7.0 and 5.7.1 draft records. GitHub has no tags or releases for those versions.
• Adds corrected 4.44.1 release notes, including the existing SDK paging and Agent Q v2/signed-envelope compatibility warnings. Renumbering does not restore compatibility.
• Makes the installer fallback avoid choosing a numerically higher tag from a different major line when the release API is unavailable.

Validation:

• version-plan --base origin/main --head HEAD: passed; target 4.44.1, major line 4, no major-line violations, historical sync checks valid.
• release-docs check --version 4.44.1: passed with no findings.
• publish-preflight --base origin/main --head HEAD: passed with no prepared changes.
• Focused version, release-document, installer, documentation-alignment, branding, and graphics-render checks are recorded in the maintenance ledger. The local broader suite encounters an ignored broken adapter-symlink fixture; full CI is the required suite gate for merge.
• All three commits are signed with the repository's required OpenPGP key; git diff --check passes.

Preserve the v5.6.2 baseline in repair mode

When v4.44.1 has been published and release-docs ... --repair --verify-baseline is used, control enters the repair branch before this new reconciliation-aware anchor handling. _prior_release() compares versions numerically, so it excludes v5.6.2 because it is greater than 4.44.1 and can select v4.22.9 instead; the repair candidate then includes the entire already-published migration history and may rewrite the 4.44.1 notes from the wrong baseline. Apply the reconciliation/published-anchor selection to repair planning as well.
