fix(codex): suppress SessionStart hook auto-discovery with empty hooks object

Codex auto-discovers a plugin's hooks/hooks.json whenever the Codex
manifest has no `hooks` field: load_plugin_hooks falls back to a
hardcoded DEFAULT_HOOKS_CONFIG_FILE = "hooks/hooks.json" and registers
it. hooks/hooks.json is the Claude Code SessionStart hook, it is tracked
in this repo, and the Codex marketplace installs the whole repo root
(source url "./"), so the fallback re-registered the SessionStart hook
and its install-time trust prompt on Codex.

Removing the Codex hook file and the manifest `hooks` pointer (commit
"Remove Codex hooks") did not disable the hook on Codex — it removed the
explicit declaration that was overriding the fallback, so the fallback
took over and found the Claude hooks/hooks.json.

Declare an empty inline hooks object ({}) in .codex-plugin/plugin.json.
It parses as an empty inline hook set and stops Codex reaching the
auto-discovery fallback. An absent field, an empty array ([]), and an
empty inline list all collapse back to the fallback, so the value must
be exactly {}.

Update the test to assert the manifest declares hooks: {} (and that
hooks/hooks.json exists, which is what makes the declaration necessary),
replacing the prior assertion that the field was absent — which passed
while the hook was still being auto-discovered.

 # Superpowers Release Notes
 
+## v6.1.0 (2026-06-30)
+
+### Lower Per-Session Token Cost
+
+The `using-superpowers` bootstrap is injected into every session, so its size is paid for constantly. This release trims it and the per-harness references it points to, without dropping behavior-shaping content.
+
+- **Compressed the `using-superpowers` bootstrap.** Replaced the graphviz skill-flow diagram with the prose it encoded, folded the standalone Instruction-Priority section into User Instructions, dropped the per-platform "How to Access Skills" walkthrough, and trimmed the Platform Adaptation pointer to the harnesses that still ship a reference file. The full Red Flags rationalization table and the user-instruction precedence rules are unchanged.
+- **Pruned the per-harness tool-mapping references.** The verbose action-to-tool tables restated guidance modern agents already follow. Each reference file is trimmed to the harness-specific notes that still carry weight — subagent dispatch, task tracking, instructions-file paths — and `claude-code-tools.md` and `copilot-tools.md`, which had nothing harness-specific left, are deleted.
+
+### Codex
+
+- **Codex can install from the marketplace.** Codex marketplace sources expect a `.agents/plugins/marketplace.json` at the marketplace root; the repo only shipped the Claude marketplace file, so Codex could name the marketplace but found no installable plugin entries. A repo-local Codex marketplace manifest now points at the same repository root, so the plugin is installable from Codex.
+- **Codex no longer ships a SessionStart hook.** Codex reliably triggers skills on its own, and the bootstrap hook made the UX worse rather than better. The Codex hook config (`hooks-codex.json`) and its manifest registration are removed.
+
+### Harness Support
+
+- **Gemini CLI support removed.** Google EOLed the Gemini CLI on 2026-06-18; the extension can no longer be installed or updated. Gemini is gone from the install docs, the subagent-capable platform lists, and the eval-harness description, and its tool-mapping reference is deleted.
+
 ## v6.0.3 (2026-06-18)
