Description

Docs tooling (tools/build-user-guide/):

• html_sop_edits.py: the "essentials gains a Rust row" append now inserts the final "Built from a clone of the repository…" text. This makes it the only edit that owns the row.
• sync-html-content.py: removed the "qs prereq row: release framing" substitution. It rewrote the text the append had just inserted, so the append's already-applied check never matched and every --apply added another row.
• sync-html-content.py: --apply now refuses to write a result that a second pass would change, and names the edits still firing. This catches any pair of edits that undo each other, not just this one.
• sync-html-content.py, html_sop_edits.py: renamed claude-sonnet-5 to claude-sonnet-5.5 in the edit tables. chore(agents): move every agent to claude-sonnet-5.5 #50 moved the HTML to the new model but not these edits, so 17 targets stopped matching and make guide-html refused to write.

Docs:

• docs/index.html and docs/site/user-guide.html: two sentences chore(agents): move every agent to claude-sonnet-5.5 #50 missed ("Every agent runs claude-sonnet-5…") now say claude-sonnet-5.5, matching agents.md and reference.md. Also removed the 4 extra "A Rust toolchain" rows (5 → 1). The decoded page diff against main only removes lines.

Fixes #48

Type of Change

• Documentation
• Other: user-guide build tooling (tools/build-user-guide/)

Testing

• sync-html-content.py --apply run 3 times in a row: the first run inserted the single row, and the next two report "no change" for both bundles, which stay byte-identical.
• The new guard, run against main's bundle with the old edit table, refuses to write and names qs prereq row: release framing.
• After rebasing onto chore(agents): move every agent to claude-sonnet-5.5 #50, the full sync-html-content.py --apply runs clean on both bundles, and a second run reports "no change".
• No claude-sonnet-5 (without .5) is left in either bundle, and they stay byte-identical.
• Rendered docs/index.html locally: Prerequisites → The essentials shows one "A Rust toolchain" row above "A terminal".

Checklist

• My code follows the style guidelines of this project (see AGENTS.md's Code Style & Conventions)
• I have performed a self-review of my own changes
• I have commented my code where necessary

Notes for Reviewers

• These existing failures are also on origin/main and are left out of scope:
  • build-user-guide.sh --check fails because feat: publish Konductor as a Claude Code plugin marketplace #28 changed docs/user-guide/**/*.md without regenerating the HTML. This PR leaves the manifest unchanged.
  • make guide-check reports one failure: "config is listed as withdrawn… but cli/README.md no longer declares it".
• Follow-up: the prerequisites row and quick start step 1 still say to build from a clone, but releases are published (v1.0.0–v1.0.3) and the README offers a binary install. Rewording that across the Markdown and HTML is a separate change.
