📝 changelog: 0.5.0 release notes

[martinciu]

📝 What

Promote ## [Unreleased] to ## [0.5.0] — 2026-06-10, covering everything merged since v0.4.0. Minor bump per the project versioning policy (minor = each release; patch reserved for hotfixes).

✨ Added

• 📊 Per-project cost & token breakdown in the TUI — a table below the chart, aggregated over the visible time window, with worktrees/subdirectories rolled up to the parent repo; hidden by default, toggled with p; compact token counts, right-aligned columns, content-sized box with the chart reclaiming spare rows (📊 Group cost & tokens by project (roll up worktrees) #408, 📊 Group cost & tokens by project (roll up worktrees) #409, 🔢 Projects breakdown: compact token counts (65k) and right-align the column #410, 🔢 Compact projects-box token counts + right-align columns #411, ⌨️ Toggle the projects breakdown box with the p key #413, 🙈 Hide the projects breakdown box by default #414, 🙈 Hide the projects breakdown box by default #415, 📐 Shrink the projects box to its content (no empty filler rows) #420, 📐 Shrink the projects box to its content (#420) #429)
• 💰 Pricing snapshot 2026-06-09 with Claude Fable 5 and Mythos 5 rates ($10 / $50 per Mtok in/out) (pricing: drift detected vs anthropic docs (2026-06-09) #418, 💰 Add 2026-06-09 pricing snapshot with Claude Fable 5 and Mythos 5 #419)

🔄 Changed

• 🗃️ Cache schema bumped to v8 (new repo_root column); existing caches rebuild automatically on first launch (📊 Group cost & tokens by project (roll up worktrees) #408)

🐛 Fixed

• 🪟 Projects box query window now follows the chart's visible time range — no more "no activity in this window" on the usage-line view after zooming/scrolling (🪟 Projects box shows "no activity in this window" on the usage-line view after zoom/scroll #430, 🪟 Fix the projects box window on the usage-line view (#430) #431)
• 🧱 Ingest writes message rows and the file cursor in one transaction; a real GetFile DB error now logs and skips instead of silently re-parsing from offset 0 (🗃️ ingest: harden ProcessFile write path — atomic cursor+rows, surface GetFile error #401, 🗃️ ingest: atomic cursor+rows write, surface GetFile error #405)

🔧 Internal

• 🎬 Regenerated demo GIF — smaller file, same tape (🎬 demo: regenerate GIF (smaller file, same tape) #399)
• ⬆️ Dependency bumps: go-deps (modernc.org/sqlite, chore(deps): bump modernc.org/sqlite from 1.51.0 to 1.52.0 in the go-deps group #406) and gha-deps (chore(deps): bump the gha-deps group with 2 updates #407)

✅ Test plan

• 📄 Docs-only change — CHANGELOG.md is the sole artifact (release version is injected via GoReleaser ldflags, nothing in source to bump); full go test ./... green locally
• 🔢 Mechanical verification: every post-v0.4.0 PR ref appears exactly once in the 0.5.0 section (📊 Group cost & tokens by project (roll up worktrees) #408 twice — legitimately cited on both the Added and Changed bullets); no Unreleased heading remains; ## [0.5.0] — 2026-06-10 sits directly above [0.4.0]

🚀 Next step (post-merge)

Tag v0.5.0 on main and push — that triggers the GoReleaser release workflow (binaries + Homebrew tap).

Closes #432.
