fix(tests): make SDD integration test actually run its assertions

The SDD integration test silently bailed before printing any verification
results. Three independent bugs caused this:

1. `WORKING_DIR_ESCAPED` was computed from `$SCRIPT_DIR/../..` without
   resolving `..` segments. The resulting "directory" name contained
   literal `..` so `find` was looking in a path that doesn't exist.

2. With `set -euo pipefail`, the `find ... | sort -r | head -1` pipeline
   could exit non-zero (SIGPIPE on the producer when head closes early),
   killing the script silently before assertions ran.

3. The `claude -p` invocation never passed `--plugin-dir`, so it loaded
   the installed plugin instead of the working tree. Local edits to
   skills under test were not actually being tested.

Other adjustments:
- Run claude from inside the unique TEST_PROJECT directory instead of
  from the plugin root, so its session JSONL lives in its own
  `~/.claude/projects/` folder and doesn't race other concurrent
  claude sessions for "most recent file".
- Use the same character-normalization claude does (every non-alphanumeric
  becomes `-`) when computing the session dir name; macOS-resolved
  `/private/var/...` paths and tmp dirs with `.`/`_` in their names need
  this to round-trip correctly.
- Accept either `"name":"Agent"` or `"name":"Task"` in the subagent count
  — the harness renamed the tool but the test wasn't updated.

Verified on this branch: all six verification tests now pass against a
real end-to-end SDD run (skill invoked, 7 subagents dispatched, 6
TodoWrite calls, working code produced, tests pass, no extra features).

 Superpowers is a complete software development methodology for your coding agents, built on top of a set of composable skills and some initial instructions that make sure your agent uses them.
 
+## Quickstart
+
+Give your agent Superpowers: [Claude Code](#claude-code), [Codex CLI](#codex-cli), [Codex App](#codex-app), [Factory Droid](#factory-droid), [Gemini CLI](#gemini-cli), [OpenCode](#opencode), [Cursor](#cursor), [GitHub Copilot CLI](#github-copilot-cli).
+
 ## How it works
 
 It starts from the moment you fire up your coding agent. As soon as it sees that you're building something, it *doesn't* just jump into trying to write code. Instead, it steps back and asks you what you're really trying to do.
