fix(omp): correct docs/counts/URLs, resolver install-path order, stray comment + CSS

Small cleanup items from upstream review (Ark0N/Codeman#353):

- OMP_SEARCH_DIRS now leads with ~/.local/bin, matching omp.sh's real
  installer target (~/.omp/bin was an earlier unverified guess, confirmed
  wrong against a real --no-cache Docker build).
- docs/omp-integration.md: fixed the dead GitHub URL (can1357/omp ->
  can1357/oh-my-pi), corrected the CLI count (ninth backend, tenth
  SessionMode incl. shell -- not eighth), matched the install-path guidance
  to the resolver fix, updated the version example to the actually-tested
  18.0.8, and added a Docker-section caveat: --resume pinning does not
  currently reach an in-container omp process, since Docker panes never see
  ompConfig.
- docs/architecture-invariants.md: fixed a heading missing ", OMP" (CLAUDE.md
  already linked to the -omp anchor, so the link was dead) and added an OMP
  specifics paragraph -- the one external CLI missing an entry in this doc.
- .changeset/omp-backend.md: corrected the sibling-CLI list (was missing Pi,
  Grok, and DeepSeek Harness) and the backend count.
- Removed a stray orphaned comment fragment in the quick-start docker branch
  and split two CSS lines that had two declarations jammed onto one line.
