v0.1.3

Fixed

• promptlib import replaced every field of an existing prompt, so a record
  like {"id": "x", "tags": "new"} blanked x's title, text and category. An
  import now changes only the fields a record supplies. It also records a new
  text's placeholders, names the record that failed, and writes nothing when
  one fails.
• With the shared background service on, $PROMPT_LIBRARY_CSV and
  $PROMPT_LIBRARY_HOME did not reach the MCP tools, so the CLI and Claude could
  use different files. They are now forwarded.
• MCP tools:
  • "false" as a string was read as true;
  • a tags string was matched letter by letter;
  • missing required arguments were accepted.
• Updates that set id, created_at or updated_at were silently ignored; they
  are now refused. An empty update is an error in MCP as it was in the CLI.
• A non-UTF-8 file, or a CSV with no id column, gave a traceback or an empty
  listing instead of an error.
• Stats counted Review and review as different tags.

Added

• A project page at https://joshuaramirez.github.io/prompt-library/ with a live
  demo that runs the plugin's search and fill-in in the browser. It is built with
  vanilla-mvc in site/ and
  published, with the diagrams, by GitHub Actions.
• render reports values no placeholder used (unused), which is usually a
  misspelt name. The CLI warns about these and about unfilled placeholders.
• Writes report any column they create (new_columns).
• promptlib --version, and help text for every command and option.

Changed

• --json works after the command as well as before it.
• CLI errors read promptlib: error: … instead of exception class names. A bad
  flag shows the subcommand's usage.
• "No prompt with that id" now exits 3 instead of 2, which is argparse's code
  for a bad command line.
• --tag accepts commas. Listings show each tag, and untitled prompts as
  (untitled). A search with no hits says so.
• Blank extra columns are left out of records.
