chore: gitignore Python build artifacts and untrack accidentally-committed caches

The previous commit (87a4cfc) used `git add -A` and pulled in __pycache__/
and *.egg-info/ files because .gitignore didn't exclude them. Untrack
those, and extend .gitignore so future `git add -A` is safe.

This is a no-op for production code; only repo hygiene.

-# molecule_plugin — Python SDK for building Molecule AI plugins
-
-A Molecule AI plugin is a directory that bundles rules, skills, and per-runtime
-install adaptors. Any plugin that conforms to this contract is installable
-on any Molecule AI workspace whose runtime the plugin supports.
-
-## Quick start
-
-Copy `template/` to a new directory and edit:
-
-```
-my-plugin/
-├── plugin.yaml              # name, version, runtimes, description
-├── rules/my-rule.md         # optional — appended to CLAUDE.md at install
-├── skills/my-skill/
-│   ├── SKILL.md             # instructions injected into the system prompt
-│   └── tools/do_thing.py    # optional LangChain @tool functions
-└── adapters/
-    ├── claude_code.py       # one-liner: `from molecule_plugin import AgentskillsAdaptor as Adaptor`
-    └── deepagents.py        # same
-```
-
-Validate:
-
-```python
-from molecule_plugin import validate_manifest
-errors = validate_manifest("my-plugin/plugin.yaml")
-assert not errors, errors
-```
-
-## CLI
-
-The SDK ships a CLI for validating Molecule AI artifacts before publishing:
-
-```bash
-python -m molecule_plugin validate plugin    my-plugin/
-python -m molecule_plugin validate workspace workspace-configs-templates/claude-code-default/
-python -m molecule_plugin validate org       org-templates/molecule-dev/
-python -m molecule_plugin validate channel   channels.yaml
-python -m molecule_plugin validate my-plugin/   # kind defaults to 'plugin'
-```
-
-Exit code is 0 when valid, 1 when any errors are found — suitable for CI.
-Add `-q` / `--quiet` to suppress success lines and emit only errors.
-
-Programmatic equivalents:
-
-```python
-from molecule_plugin import (
-    validate_plugin,
-    validate_workspace_template,
-    validate_org_template,
-    validate_channel_file,
-    validate_channel_config,
-)
-```
-
-## Per-runtime adaptors — when to write a custom one
-
-The default `AgentskillsAdaptor` handles the common shape: rules go into
-the runtime's memory file (CLAUDE.md), skill dirs go into `/configs/skills/`.
-That covers most plugins.
-
-Write a custom adaptor when you need to:
-
-- **Register runtime tools dynamically** — call `ctx.register_tool(name, fn)`.
-- **Register DeepAgents sub-agents** — call `ctx.register_subagent(name, spec)`.
-- **Write to a non-standard memory file** — call `ctx.append_to_memory(filename, content)`.
-
-Minimum custom adaptor:
-
-```python
-# adapters/deepagents.py
-from molecule_plugin import InstallContext, InstallResult
-
-class Adaptor:
-    def __init__(self, plugin_name: str, runtime: str):
-        self.plugin_name, self.runtime = plugin_name, runtime
-
-    async def install(self, ctx: InstallContext) -> InstallResult:
-        ctx.register_subagent("my-agent", {"prompt": "...", "tools": [...]})
-        return InstallResult(plugin_name=self.plugin_name, runtime=self.runtime, source="plugin")
-
-    async def uninstall(self, ctx: InstallContext) -> None:
-        pass
-```
-
-## Resolution order (understood by the platform)
-
-For `(plugin_name, runtime)`:
-
-1. **Platform registry** — `workspace-template/plugins_registry/<plugin>/<runtime>.py`
-   (curated; set by the Molecule AI team for quality-assured plugins).
-2. **Plugin-shipped** — `<plugin_root>/adapters/<runtime>.py` (what this SDK helps you build).
-3. **Raw-drop fallback** — copies plugin files into `/configs/plugins/<name>/`
-   and surfaces a warning; no tools are wired.
-
-You generally ship for path #2. If your plugin becomes popular enough to be
-promoted to "default," the Molecule AI team PRs a copy of your adaptor into
-the platform registry (path #1) so it survives upstream breakage.
-
-## Testing locally
-
-The SDK ships `AgentskillsAdaptor` as a standalone, unit-testable class:
-
-```python
-import asyncio
-from pathlib import Path
-from molecule_plugin import AgentskillsAdaptor, InstallContext
-
-ctx = InstallContext(
-    configs_dir=Path("/tmp/configs"),
-    workspace_id="local",
-    runtime="claude_code",
-    plugin_root=Path("./my-plugin"),
-)
-asyncio.run(AgentskillsAdaptor("my-plugin", "claude_code").install(ctx))
-# check /tmp/configs/CLAUDE.md, /tmp/configs/skills/
-```
-
-## Publishing
-
-A plugin is just a directory. Push it to any Git host. Installation via
-`POST /plugins/install {git_url}` is on the roadmap — see the platform's
-`PLAN.md` under "Install-from-GitHub-URL flow." Until then, plugins are
-bundled into the platform by dropping them into `plugins/` at deploy time.
-
-## Supported runtimes
-
-As of 2026-Q2: `claude_code`, `deepagents`, `langgraph`, `crewai`, `autogen`,
-`openclaw`. See the live list with:
-
-```bash
-curl $PLATFORM_URL/plugins
-```
