Summary

Multiple simultaneous partners were already supported (MATRIMONY_MAX_PARTNERS, default unlimited). This PR adds the missing piece for polyamorous marriages: when a user takes a new partner, every existing partner of both spouses is notified with an immediate accept-or-divorce choice — plus three community requests: bot-directed quips, slash command support, and a few new fun commands.

Polyamory notices

1. !matr marry @user → proposal as before. If either side already has partners, the proposal message now says those partners will be notified.
2. The target accepts → the marriage forms immediately, regardless of existing partners. No consent gate.
3. Each existing partner (of the proposer and of the target) gets a notice in the channel with Accept and Divorce buttons, plus text equivalents.
   • Accept (!matr accept): acknowledgement only — the notice is cleared, nothing else changes.
   • Divorce (!matr divorce @partner or the button): ends that partner's own marriage to the spouse via the normal divorce path (remove_partners — so divorce, abandon, forcedivorce all behave consistently).
4. An ignored notice never undoes or blocks anything.

• store.py: new notices table (user_id = partner being told, spouse_id = their partner who remarried, other_id = the new spouse) + Notice dataclass and CRUD. remove_partners clears notices that presume the dissolved marriage, so divorce/abandon/forcedivorce can't leave stale ones. stats() gains partner_notices.
• cogs/matr.py: _notify_new_partners runs after a marriage is enacted (proposals and forcemarry) and posts one notice per existing partner with a PartnerNoticeView (buttons restricted to that partner, 24h window). matr_accept picks from proposals and notices (_pick_answerable); matr_decline stays proposal-only but points notice-holders at divorce.

Bot-directed quips

• Aiming an action at Matrimony itself appends a rotating quip as Discord subtext (-# line) under the normal reply — one quip set per command (_BOT_QUIPS, itertools.cycle rotation).
• Proposals at the bot (marry/adopt/makeparent) are declined outright with a quip — e.g. "sorry, taken by discord.py" — and no proposal is created.

Slash commands

• Every !matr command is now a discord.py hybrid command, so /matr mirrors the prefix surface exactly.
• Discord caps a slash group at 25 children and the bot has ~50, so /matr holds the core family commands while the rest nest one level: /matr fun hug, /matr admin forcemarry, /matr meta stats. The group's app_command is detached during decoration and the tree is assembled in the Registration section.
• commands.guild_only / commands.has_permissions were mirrored with app_commands.guild_only() / app_commands.default_permissions() so the slash side inherits the same restrictions.
• setup_hook calls tree.sync() to publish the commands at startup.

New fun commands

• flirt @user (alias rizz) — a terrible pickup line + GIF.
• date @user (alias dateidea) — a terrible date idea + GIF.
• anniversary [@partner] (alias anniv) — time married (via store.partnership_since); defaults to your only partner.

No economy, currency, or inventory — just relational jokes.

Tests

27 new tests (98 total): notice lifecycle/fan-out/divorce paths; quip append/no-quip/rotation and bot-declines; flirt/date/anniversary callbacks; slash tree layout, subgroup contents, lowercase-name rule, guild_only/default_permissions propagation, and prefix-side parity. pytest and ruff check are clean.
