Move workflow distribution from API to GitHub registry

gcontext add resolves against bleak-ai/workflows tarball (or any public GitHub repo URL via GCONTEXT_REGISTRY); gcontext share validates locally and prints the PR submission flow; init creates secrets.env with mode 600 and up warns if permissions are open; README updated for the new CLI surface. Version bump to 0.5.0. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>

+Markdown holds the context, YAML holds the config. Edit any of it with a text editor; the server reads the files on demand, so changes apply immediately. Two exceptions load at server start and need a restart to pick up edits: `agent.md` (pushed in the MCP handshake) and command files. The server warns when these files change: in the `write_file` result, and with a line on the server terminal.

 At connect, every agent receives two layers of instructions through the handshake: first gcontext's own fixed instructions (shipped with the package, they explain the tools and the folder conventions), then your `agent.md` (what this particular agent is). You only ever write the second layer.

 That's it. The server picks the connection up on the next tool call (no restart), `gcontext status` shows whether every declared secret has a value, and the agent can now call the API through `run_adhoc_script` and `run_script` without ever seeing the key.

 ## Context ledger

 `gcontext context` lists every channel through which context reaches the agent, marked as `loaded` (pushed at connect), `on demand` (agent pulls it via a visible tool call), `skipped` (nothing to push), or `uncontrolled` (owned by the runtime, outside gcontext's view). gcontext only inserts context through the channels on that list. If you want to know what the agent is seeing, this is the answer.

 `connection.yaml` declares secret names; `secrets.env` holds the values. When the agent calls `run_script` or `run_adhoc_script`, the values are injected as environment variables and scrubbed from the script's output. The agent can know that `STRIPE_API_KEY` exists and use it in a script, but never reads the value. `secrets.env` is gitignored by `init` and the `write_file` tool refuses to touch it.

+One honest caveat: `secrets.env` is plain text on disk. gcontext never shows
+values to the agent, but any other program with filesystem access, including
+your AI client's own file tools, can read the file directly. `init` creates it
+with mode 600 and gitignores it. If your client supports permission rules,
+deny it read access to `secrets.env` as well.
+
 Both tools execute Python in a per-project venv with each connection's declared deps preinstalled (via uv).
