docs(tooling): T-1253 — sweep the live references to retired tool paths

A script scanned every tracked doc, rule, skill, agent, hook and source file
for tooling/ paths that no longer exist, skipping historical records (sprints,
discussions, workshops, governance, generated wiki pages). It found 62. The
ones that tell a reader what to RUN now name the reach verb:

- The atlas skill still sent agents to tooling/atlas, atlas-verify,
  atlas-update-field and atlas-commit-and-sync — about forty lines, all
  retired in T-1285. They now name the `reach atlas` verbs, and the skill
  records that commit-and-sync STAGES by default (--commit to commit) and
  takes --corridor as an option.
- The clerk agent named tooling/clerk-review (now `reach dev clerk`). The Si
  and clerk briefings sent those agents to the retired tooling/db/decision
  and sqlite-query CLIs and to decisions/*.md paths that moved to
  governance/ in the pql migration. They now name pql.
- The ticket-cli rule documented `pql decisions read`, which does not exist;
  `show` already includes the body.
- The culture authoring guide and the RON sources name
  `reach validate ron`, with the same arguments as before.
- The 41 Blender payloads' usage lines ran the retired tooling/blender
  wrapper, and the docstrings still cited pre-carve-out paths. They now read
  `reach blender run <payload>`.
- Doc comments in server/, client/, wiki TOMLs and the domain modules.

What is left is deliberate: "Formerly …" provenance, dated plans and findings
docs, the retired-pipeline doc, and a build-artefact path.

project.yaml 0.4.14 (mirrored to the client). Comment-only, but four touched
files are in the canvas-version registry (trait_catalog_reader.rs, since
T-1289, canvas_sources.py itself, and two client files). The gate is
path-based and has no override. The previous push was rejected on exactly
this.

Three of the edits are stamped ledger sources, so systems.db is regenerated
and the stamp is fresh.
