v1.3.0 — iroh QUIC, card links, mentions, deep links, chat CLI

What's new in v1.3.0

Net layer — iroh QUIC transport

• Replaced libp2p v0.53 with iroh 1.0.1 — QUIC-native P2P sync, no more libp2p complexity
• Protocol version negotiation — VersionHello/VersionReject exchange on every new connection; incompatible peers are cleanly rejected
• Peer presence heartbeats — SyncRequest::Presence broadcast every 30 s; recipients update space_members.presence in SQLite
• HLC remote clock — clock::observe_remote() advances the logical counter from any remote HLC string

Card links (CRDT)

• add_card_link / remove_card_link / list_card_links in monotask-core::card
• Stored as a links Map on the Automerge card object
• Exposed as add_card_link_cmd / remove_card_link_cmd / list_card_links_cmd Tauri commands
• CLI: monotaskcli card link add/list/remove

@Mention scanning

• index_mentions() scans card descriptions for @token patterns after every update_card_cmd
• Results indexed in mention_index SQLite table
• CLI: monotaskcli card mentions <BOARD_ID> <CARD_ID>

Deep links

• monotask://board/<id> and monotask://board/<id>/card/<id> registered via tauri-plugin-deep-link
• Deep link events forwarded to JS, which navigates to the board/card automatically
• CLI: monotaskcli app open <url>

New CLI commands

• monotaskcli board undo/redo — undo/redo via SQLite stack
• monotaskcli chat send/list — send and list chat messages per space
• monotaskcli card link add/list/remove — card-to-card links
• monotaskcli card mentions — query @mention index
• monotaskcli app open <url> — open deep link in desktop app

CLI binary renamed

• Binary is now monotaskcli (was monotask) — resolves output filename collision with the Tauri app binary
• monotask binary is now exclusively the Tauri desktop app

Quality

• Zero compiler warnings across all workspace crates
• Integration tests updated: make_space helper, --space flag threading, board list object format
• All 100+ tests passing (0 failures)
