fix(plugin-dev): add missing .claude-plugin/plugin.json manifest

The plugin-dev plugin is listed in .claude-plugin/marketplace.json but was the
only plugin in the plugins/ directory without a .claude-plugin/plugin.json
manifest, which is required for installation from the marketplace.

Adds the manifest with name, version, description, and author matching the
marketplace.json entry, consistent with all other plugins in this repo.

 # Changelog
 
-## 2.1.108
-
-- Added `ENABLE_PROMPT_CACHING_1H` env var to opt into 1-hour prompt cache TTL on API key, Bedrock, Vertex, and Foundry (`ENABLE_PROMPT_CACHING_1H_BEDROCK` is deprecated but still honored), and `FORCE_PROMPT_CACHING_5M` to force 5-minute TTL
-- Added recap feature to provide context when returning to a session, configurable in /config and manually invocable with /recap; force with `CLAUDE_CODE_ENABLE_AWAY_SUMMARY` if telemetry disabled.
-- The model can now discover and invoke built-in slash commands like `/init`, `/review`, and `/security-review` via the Skill tool
-- `/undo` is now an alias for `/rewind`
-- Improved `/model` to warn before switching models mid-conversation, since the next response re-reads the full history uncached
-- Improved `/resume` picker to default to sessions from the current directory; press `Ctrl+A` to show all projects
-- Improved error messages: server rate limits are now distinguished from plan usage limits; 5xx/529 errors show a link to status.claude.com; unknown slash commands suggest the closest match
-- Reduced memory footprint for file reads, edits, and syntax highlighting by loading language grammars on demand
-- Added "verbose" indicator when viewing the detailed transcript (`Ctrl+O`)
-- Added a warning at startup when prompt caching is disabled via `DISABLE_PROMPT_CACHING*` environment variables
-- Fixed paste not working in the `/login` code prompt (regression in 2.1.105)
-- Fixed subscribers who set `DISABLE_TELEMETRY` falling back to 5-minute prompt cache TTL instead of 1 hour
-- Fixed Agent tool prompting for permission in auto mode when the safety classifier's transcript exceeded its context window
-- Fixed Bash tool producing no output when `CLAUDE_ENV_FILE` (e.g. `~/.zprofile`) ends with a `#` comment line
-- Fixed `claude --resume <session-id>` losing the session's custom name and color set via `/rename`
-- Fixed session titles showing placeholder example text when the first message is a short greeting
-- Fixed terminal escape codes appearing as garbage text in the prompt input after `--teleport`
-- Fixed `/feedback` retry: pressing Enter to resubmit after a failure now works without first editing the description
-- Fixed `--teleport` and `--resume <id>` precondition errors (e.g. dirty git tree, session not found) exiting silently instead of showing the error message
-- Fixed Remote Control session titles set in the web UI being overwritten by auto-generated titles after the third message
-- Fixed `--resume` truncating sessions when the transcript contained a self-referencing message
-- Fixed transcript write failures (e.g., disk full) being silently dropped instead of being logged
-- Fixed diacritical marks (accents, umlauts, cedillas) being dropped from responses when the `language` setting is configured
-- Fixed policy-managed plugins never auto-updating when running from a different project than where they were first installed
-
-## 2.1.107
-
-- Show thinking hints sooner during long operations
-
 ## 2.1.105
 
 - Added `path` parameter to the `EnterWorktree` tool to switch into an existing worktree of the current repository
