docs: re-anchor Shape A examples away from Codex

hooks/session-start-codex has had no caller since "Remove Codex hooks"
(#1845) deleted hooks-codex.json and its manifest registration; the
Codex manifest now declares an empty hooks object so Codex registers no
session-start hook at all. The script is Codex-specific dead code —
nothing executes it on Codex or any other harness.

- Delete hooks/session-start-codex.
- tests/hooks/test-session-start.sh: drop the two Codex cases that are
  redundant with the generic session-start tests (nested-format and the
  legacy-warning omission are already covered by the Claude Code cases).
  Re-point the "wrapper dispatches" case to the live `session-start`
  script so run-hook.cmd dispatch coverage — used by Claude Code and
  Cursor in production — is preserved rather than lost.
- docs/porting-to-a-new-harness.md: Codex is no longer a Shape A
  (shell-hook) harness, so re-anchor that worked example to Cursor (a
  live shell-hook harness that demonstrates the same per-harness field,
  schema, and matcher variance) and mark Codex as native skill discovery
  with no session-start hook. Clears the references to the deleted
  hooks-codex.json.
- docs/windows/polyglot-hooks.md: the "check hooks-codex.json" pointer
  referenced a file deleted in #1845; re-point to hooks-cursor.json.

RELEASE-NOTES.md keeps its historical mention of hooks-codex.json (it
accurately records what that release did). The tests/codex-plugin-sync
fixtures build their own synthetic session-start-codex and test the sync
mechanism generically, so they are intentionally left as-is.

 # Superpowers Release Notes
 
-## v6.1.1 (2026-07-02)
-
-### Codex
-
-- **Codex no longer re-registers the Claude SessionStart hook.** v6.1.0 removed the Codex hook config and its manifest `hooks` pointer, meaning to stop Codex from installing a SessionStart hook — but with no `hooks` field, Codex fell back to auto-discovering `hooks/hooks.json`, the Claude Code SessionStart hook that the marketplace ships from the repo root, and re-registered it along with its install-time trust prompt. The Codex manifest now declares an explicit empty hooks object (`hooks: {}`), which Codex reads as "no hooks" instead of reaching the auto-discovery fallback. An absent field, `[]`, and an empty inline list all collapse back to the fallback, so the value has to be exactly `{}`.
-- **Removed orphaned Codex session-start dead code.** `hooks/session-start-codex` had no caller once the Codex hook config was deleted, so it and its redundant test cases are gone. The worked shell-hook example in `docs/porting-to-a-new-harness.md` moves from Codex — now native skill discovery with no session-start hook — to Cursor, a live shell-hook harness, and the stale `hooks-codex.json` pointer in `docs/windows/polyglot-hooks.md` is corrected. The Codex plugin category is also fixed to "Developer Tools".
-
-### Packaging
-
-- **New `package-codex-plugin.sh` for building the Codex portal package.** A maintainer script produces a deterministic Codex "portal" archive — `.zip` by default, `tar.gz` on request — that normalizes entry timestamps, preserves executable modes, verifies every packaged skill ships its OpenAI metadata, includes the app and composer icons, and refuses to run against a dirty worktree. The packaged manifest keeps the source `hooks: {}` object so a portal-installed plugin avoids the same SessionStart auto-discovery, and the script can rebuild a byte-identical archive from a saved metadata source. Covered by a new test suite.

-# Gemini CLI Tool Mapping
-
-Skills speak in actions ("dispatch a subagent", "create a todo", "read a file"). On Gemini CLI these resolve to the tools below.
-
-| Action skills request | Gemini CLI equivalent |
-|----------------------|----------------------|
-| Read a file | `read_file` |
-| Read multiple files at once | `read_many_files` |
-| Create a new file | `write_file` |
-| Edit a file | `replace` |
-| Run a shell command | `run_shell_command` |
-| Search file contents | `grep_search` |
-| Find files by name | `glob` |
-| List files and subdirectories | `list_directory` |
-| Fetch a URL | `web_fetch` |
-| Search the web | `google_web_search` |
-| Invoke a skill | `activate_skill` |
-| Dispatch a subagent (`Subagent (general-purpose):` template) | `invoke_agent` with `agent_name: "generalist"` (invocable via `@generalist` chat syntax — see [Subagent support](#subagent-support)) |
-| Multiple parallel dispatches | Multiple `invoke_agent` calls in the same response |
-| Task tracking ("create a todo", "mark complete") | `write_todos` (statuses: pending, in_progress, completed, cancelled, blocked) |

-
-When a skill mentions "your instructions file", on Gemini CLI this is **`GEMINI.md`**. Gemini CLI loads `GEMINI.md` hierarchically: global at `~/.gemini/GEMINI.md`, project-level files in workspace directories and their ancestors, and sub-directory `GEMINI.md` files when a tool accesses files in those directories.
-
-## Personal skills directory
-
-User-level skills live at **`~/.gemini/skills/`**, with **`~/.agents/skills/`** as a cross-runtime alias (shared with Codex and Copilot CLI). When both directories exist at the same scope, `.agents/skills/` takes precedence. Each skill is a subdirectory containing a `SKILL.md` (with `name` and `description` frontmatter).
-
-## Subagent support
-
-Gemini CLI dispatches subagents through the `invoke_agent` tool, which takes `agent_name` and `prompt` parameters. The same dispatch is also surfaced as a chat-syntax shortcut: typing `@generalist <prompt>` is equivalent to calling `invoke_agent` with `agent_name: "generalist"`. Built-in agent names include `generalist`, `cli_help`, `codebase_investigator`, and (with browser tooling enabled) `browser_agent`.
-
-Skills dispatch with `Subagent (general-purpose):` and either reference a prompt-template file (e.g., `superpowers:subagent-driven-development`'s `./implementer-prompt.md`) or supply an inline prompt. On Gemini CLI:
-
-| Skill dispatch form | Gemini CLI equivalent |
-|---------------------|----------------------|
-| References a `*-prompt.md` template (implementer, task-reviewer, code-reviewer, etc.) | Fill the template, then `invoke_agent` with `agent_name: "generalist"` and the filled prompt |
-| References `superpowers:requesting-code-review`'s `./code-reviewer.md` | `invoke_agent` with `agent_name: "generalist"` and the filled review template |
-| Inline prompt (no template referenced) | `invoke_agent` with `agent_name: "generalist"` and your inline prompt |
-
-### Prompt filling
-
-Skills provide prompt templates with placeholders like `{WHAT_WAS_IMPLEMENTED}` or `[FULL TEXT of task]`. Fill all placeholders before passing the complete prompt to `invoke_agent`. The prompt template itself contains the agent's role, review criteria, and expected output format — the subagent will follow it.
-
-### Parallel dispatch
-
-Gemini CLI supports parallel subagent dispatch. Issue multiple `invoke_agent` calls in the same response (or multiple `@generalist` invocations in one prompt) to run independent subagent work in parallel. Keep dependent tasks sequential, but do not serialize independent subagent tasks just to preserve a simpler history.
-
-## Additional Gemini CLI tools
-
-These tools are unique to Gemini CLI:
-
-| Tool | Purpose |
-|------|---------|
-| `save_memory` (legacy) | Persist facts across sessions when `experimental.memoryV2 = false` |
-| `get_internal_docs` | Look up Gemini CLI's bundled documentation |
-| `ask_user` | Pose structured questions to the user (text / single-select / multi-select) |
-| `enter_plan_mode` / `exit_plan_mode` | Switch into and out of read-only plan mode |
-| `update_topic` | Update the current conversation's topic / strategic-intent metadata |
-| `complete_task` | Signal that a Gemini subagent has completed and return its result to the parent agent |
-| `tracker_create_task`, `tracker_update_task`, `tracker_get_task`, `tracker_list_tasks`, `tracker_add_dependency`, `tracker_visualize` | Rich task tracker with dependency and visualization support |
-| `read_mcp_resource`, `list_mcp_resources` | MCP resource access |

 You write test cases (pressure scenarios with subagents), watch them fail (baseline behavior), write the skill (documentation), watch tests pass (agents comply), and refactor (close loopholes).
