Adds Hamilton Helmer's 7 Powers framework skill for assessing durable
competitive advantage (scale economies, network effects, counter-
positioning, switching costs, branding, cornered resource, process
power). Updates skill counts and descriptions across marketplace.json,
plugin.json, and READMEs.
Merged from louzhedong:codex/add-seven-powers-skill (PR vs phuryn/pm-skills).

Codex CLI (0.136+) reads the same .claude-plugin/marketplace.json as Claude
Code, so PM Skills installs natively via `codex plugin marketplace add` — no
file-copying required.
- Add a first-class "Codex CLI (OpenAI)" install section (marketplace add +
per-plugin `codex plugin add`).
- Note the difference vs. Claude Code: skills work and are invocable by name;
`/slash` commands install but do not run as Codex slash commands.
- Document an optional path: ask Codex to convert the bundled command files
into skills (best-effort, model-driven).
- Remove the now-inaccurate "copy skills to .codex/skills/ — Skills only" row
from the "Other AI assistants" table.
Docs-only; no plugin/marketplace contents changed (counts unchanged, no
version bump). Validator: all 9 plugins pass.

- Delete .docs/images/plugins-overview.webp (already replaced by plugins.png in v2.0.0).
- Delete .docs/images/how-skills-work.webp and its reference in README.md.

Relocate image assets into .docs/images and update README image references accordingly. Four files were renamed/moved: add-marketplace.webp, how-skills-work.webp, plugins-overview.webp, and pm-skills-install.gif; README.md paths were updated to point to .docs/images/*. Keeps documentation assets organized under .docs/images.
