test: split wt.bats into one file per command

[stilliard]

Summary

Stacked on #2 (this PR targets that branch, not main, since it splits out the --claude tests added there).

• test/wt.bats → one file per command: test/resolve.bats, cd.bats, ls.bats, mk.bats, rm.bats, prune.bats, merged.bats, help.bats
• Shared setup()/teardown() extracted to test/helpers.bash, loaded per-file with load helpers
• --claude flag tests moved to test/claude/ls.bats and test/claude/merged.bats, kept separate from each command's core behavior tests
• No test content changed — same 53 tests, same assertions, just reorganized
• README updated: bats -r test (recursive, since tests now live in a subdirectory)

Test plan

• bats -r test — 53/53 passing (same count as before the split)

Pull request overview

This PR reorganizes the Bats test suite for wt by splitting the monolithic test/wt.bats into per-command test files, extracting shared setup/teardown helpers, and isolating --claude integration tests under a dedicated subdirectory. It also updates the README to reflect running the suite recursively.

Changes:

• Split test/wt.bats into separate test/*.bats files (plus test/claude/*.bats for --claude coverage).
• Extract shared setup() / teardown() logic into test/helpers.bash and load it per test file.
• Update README test instructions to use bats -r test.

• The stub jq wrapper uses an unquoted $(command -v jq) expansion, which can break if the resolved path contains whitespace (word-splitting). Quote the resolved path before exec.

  cat > "$stubbin/jq" <<EOF
#!/usr/bin/env bash
exec $(command -v jq) "\$@"
EOF
  chmod +x "$stubbin/jq"
