IDEAgentHub: baixar versions anteriors

v1.0.4 — Antigravity sync restored, multi-monitor fixes, perpetual licences

Upgrading from 1.0.2, so this also covers 1.0.3.

- Antigravity: Sync and Replay work again after Antigravity's update split it
into two apps and moved its data. Both are now read from transcript.jsonl on
disk, across ~/.gemini/antigravity and ~/.gemini/antigravity-ide. Opening a
folder in Antigravity works again as well.
- Multi-monitor: dragging between displays with different scaling no longer
snaps the window back to the corner; maximise/restore behaves on mixed-DPI
setups, and restore now yields a comfortable size instead of a near
full-screen clone. Embedded IDEs rescale when the host crosses a DPI
boundary.
- VS Code (Copilot): user prompts are recovered from Copilot's chat session
store, fixing handoff blocks that showed "(assistant initiative)" with no
prompt on Copilot 0.57 / VS Code 1.129.
- Licensing: support for the pay-once Basic / Personal / Team tiers. Usage
never expires; the one-year update entitlement is tracked separately and the
status chip reports it correctly. A new key can be entered in-app when a
licence has expired.
- Replay storage moved to ~/.agenthub/replay/{workspace-hash} with cascade
delete, backup retention and turn-log compaction; new snapshot blobs are
Brotli compressed and existing ones still read.
- Sync: handoff toast, clickable warning pill, Sync Activity window, global
MCP server registration, smaller workspace footprint.
- Internal anti-tamper hardening with no behaviour change for licensed users.

In-place upgrade preserves the licence cache and the trial timer; caches
written by older versions keep working and nobody has to re-activate.

v1.0.2 — rebrand display name to IDEAgentHub + UI polish

- Start-menu shortcut + Add/Remove Programs entry now read "IDEAgentHub"
so Windows Start search ("IDEAgentHub") finds the app immediately.
- Product Name in File Explorer Properties matches.
- Account dashboard: self-service device revoke (soft tombstone, 1-trial-
per-machine still enforced) + Polar Customer Portal handoff for billing.
- License sign-in: email + license key form (no magic-link round trip).
- Status-bar license chip with days-left countdown.
- Trial gate hardening: HWID Tier-1 mandatory + Polar customer_id dedup +
lifetime HWID cap (10 distinct machines per license).
- Daily anti-abuse scan flags suspected sharing rings.

No breaking changes for existing 1.0.1 installs — auto-update via Velopack
preserves the license cache and the trial timer.
