chore(release): v0.4.5

[rmyndharis]

Release v0.4.5 — a Baileys quality/correctness patch plus a chat-history enhancement.

Included (already merged to main)

• feat(engine): engine-neutral WhatsApp identities (Baileys inbound conformance) #342 engine-neutral Baileys inbound ids (@c.us)
• fix(baileys): allow sending captions with document messages #363 Baileys document captions (engine parity)
• fix(baileys): show saved/contact names in the Chats list (#369) #370 (closes [Feature]: Show saved contact / push names in the dashboard Chats list (Baileys returns raw JID/@lid instead of the name) #369) Baileys Chats list shows saved/contact names
• feat(message): opt-in deep chat history (deep=true) (#347) #371 (closes [Bug/Feature]: Unable to get full chat history #347) opt-in deep=true chat history (ceiling 2000, metadata-only)
• fix(baileys): resolve @lid senders to a phone number (#362) #372 (closes Baileys engine: @lid -> phone never resolves (senderPhone / contacts/:id/phone always null); #263 feature non-functional on Baileys #362) Baileys @lid → phone resolution via the inbound message key

Release chores in this PR

• Version bump 0.4.4 → 0.4.5: package.json, dashboard/package.json, src/config/swagger.config.ts, README + docs version badges, docs/07-api-collection.md, docs/13-horizontal-scaling.md image tags, docs/15-project-roadmap.md range.
• CHANGELOG: consolidated [Unreleased] → [0.4.5] - 2026-06-20 with a summary, and added the missing fix(baileys): allow sending captions with document messages #363 entry. Fresh empty [Unreleased] left at the top.

⚠️ Behavior change to note

message.received / revoked / reaction webhook + WebSocket payloads from a Baileys session now carry @c.us ids where they previously carried @s.whatsapp.net (or a resolved @lid). A consumer that stored or compared the old ids will see the new value. whatsapp-web.js is unaffected; outbound sending and contact/chat list ids are unchanged.

Verification

• Backend: eslint clean, nest build clean, jest 942/942 pass (86 suites).
• Dashboard: vite build OK, eslint 0 errors (3 pre-existing warnings).

After merge: tag v0.4.5 → release.yml publishes the multi-arch GHCR image and creates the GitHub Release from the CHANGELOG section.
