Initialize repository with harness code and assets

Initial import of all source code, config, and README assets: the
packages workspace (cli, core, server, web, docs, landing, skills),
build scripts, tooling config, and CI workflows.

Includes the data-layout revision made on this branch: the local data
root defaults to ~/.penguin/data (PENGUIN_HOME still overrides; the
installer keeps its binaries in ~/.penguin), and every Agent lives
under <project>/agents/<agent>/ — path helpers, the three
agent-enumeration scans, the system prompt, built-in Skills, tests
and docs all follow the new layout.

+# @prismshadow/penguin-skills
+
+The PenguinHarness built-in skill library. A Skill is a directory with a `SKILL.md` (frontmatter: name, description, version, updated) — files are the runtime source of truth and ship raw in this package's npm tarball.
+
+Skills follow the "index first, body on demand" design: only their metadata is injected into an Agent's system prompt; the Agent reads the full `SKILL.md` via shell when it actually needs it.
+
+Included skills:
+
+| Group | Skills |
+| --- | --- |
+| Agent Development | `agent-creation`, `benchmark-design`, `agent-evaluation`, `agent-optimization` |
+| Data Analysis | `data-analysis` |
+| Penguin Development | `penguin-sdk`, `penguin-cli`, `agenthub-models` |
+| Web Development | `web-design` |
+| Software Engineering | `software-engineering` |
+
+The first group powers the self-improvement loop: design a Benchmark, evaluate the Target Agent, optimize it to version N+1 with a snapshot before every round.
