chore: bump version to 0.8.7, add changelog entry

Skips 0.8.6 to match mac-v0.8.7 and keep CLI + menubar versions aligned.
CLI change: MiniMax-M2.7 and MiniMax-M2.7-highspeed pricing. macOS menubar
change: three stability fixes culminating in the App Nap opt-out that keeps
the refresh loop ticking while the icon is idle in the background.

 # Changelog
 
+## 0.8.7 - 2026-04-21
+
+### Added
+- **MiniMax-M2.7 and MiniMax-M2.7-highspeed pricing.** Added to `FALLBACK_PRICING` plus display names so MiniMax sessions show up with the right cost and readable labels when users route MiniMax through providers like OpenCode. Rates verified against MiniMax's live paygo pricing: base model $0.3/M input, $1.2/M output; highspeed $0.6/M input, $2.4/M output; cache read $0.06/M, cache write $0.375/M on both.
+
+### Fixed (macOS menubar, shipped alongside via mac-v0.8.7)
+- **Menubar label froze in the background and only refreshed when you clicked the icon.** Three independent causes fixed:
+  - `prefetchAll` on launch spawned four concurrent `codeburn` subprocesses that competed with the main refresh loop for disk and parser time. Removed; period tabs now fetch lazily on first click.
+  - `NSStatusItem` sometimes deferred the status bar paint for an accessory app, so `attributedTitle` updates hit memory but not the screen until the popover opened. Explicit `needsDisplay` + `display()` after each update forces the paint.
+  - **The real root cause:** macOS App Nap / Automatic Termination was suspending the app whenever the icon sat idle in the background, stretching the 15-second refresh Task's sleep indefinitely. Holding a `ProcessInfo.beginActivity` token for the life of the app opts out. Confirmed via `log show`: `_kLSApplicationWouldBeTerminatedByTALKey` now stays at 0.
+- Subprocess `QualityOfService` lifted to `.userInitiated` so `codeburn` runs at terminal speed when spawned from the menubar.
+
+### Skipped
+- 0.8.6 was never published to npm. The version was briefly planned and then skipped to align CLI and macOS menubar versioning at 0.8.7.
+
+### Notes
+- CLI behaviour is identical to 0.8.5 aside from the MiniMax pricing addition. If you are on 0.8.5 and do not use MiniMax, you can safely stay there.
+- macOS menubar users on `mac-v0.8.6` or earlier should update: the refresh loop only ticks reliably from `mac-v0.8.7` onward. The in-app update pill surfaces within 2 days, or quit and re-run `npx codeburn menubar` to pull immediately.
