ostrakon v0.3.0

Added

• A logo: a pottery shard. The mark, lockups and icons are in brand/, the README opens with it, and the phone app uses it for its icons, its tab and beside its name.
• Install just the mod from Claude Code: claude plugin marketplace add gaius-codius/ostrakon, then claude plugin install ostrakon@ostrakon. ostrakon doctor recognises that install, and warns if the mod is also loaded through CLAUDE_CODE_PLUGIN_DIRS; install.sh doesn't load it a second time.
• Claude can read and close notes: a notes tool lists the notes waiting in this project, another or all of them, with their ids, and an archive tool archives one once its work is done (u in the pane undoes it).
• Claude's jot takes an optional project, so a note about another project lands there.

Changed

• Claude's jot doesn't save a note that's already waiting in the project with the same text; it replies with that note's id. A saved jot's reply gives its id too.
• Harvest doesn't propose a note that's already waiting in the project, or the same note twice from one review.
