CB-623: point every path at fleet/fleetd after the org transfer

The repo moved lms/claude-bridge -> fleet/claude-bridge -> fleet/fleetd.
Gitea redirects hold, so most of this is not urgent, but one line was a
real break: the implementer skill posts a worker's PR to a hardcoded
repo path, so every worker PR would have gone to the old address.

  .claude/skills/implementer/SKILL.md  the worker PR endpoint (functional)
  .gitmodules                          wiki submodule URL
  CLAUDE.md + wiki/7-Use-Cases.md      the canonical block, kept byte-identical
  README.md                            clone command and wiki link
  deploy/bridged.service               Documentation=
  plugin/.claude-plugin/plugin.json    homepage + repository
  docs/*.md                            issue and wiki links

The wiki is not a separate repo. /repos/lms/claude-bridge.wiki returns 404
and lms owned no .wiki entity, so the wiki moved with the repo; both the old
and the new wiki SSH URLs resolve to the same sha. Ticket step 4 assumed a
second transfer that does not exist.
