feat(plugin): release v2.39.0 with community contributions

Bump plugin to 2.39.0 with features from Matt Van Horn (@mvanhorn):
context budget precheck, plan sequence numbers, review serial mode,
agent-browser debugging commands, test-browser port detection, lfg
phase gating, and Context7 API key auth.

Also fixes MCP server merge order so plugin servers correctly
overwrite stale entries during sync.

+## [2.39.0] - 2026-03-10
+
+### Added
+
+- **ce:compound context budget precheck** — Warns when context is constrained and offers compact-safe mode to avoid compaction mid-compound ([#235](https://github.com/EveryInc/compound-engineering-plugin/pull/235))
+- **ce:plan daily sequence numbers** — Plan filenames now include a 3-digit daily sequence number (e.g., `2026-03-10-001-feat-...`) to prevent collisions ([#238](https://github.com/EveryInc/compound-engineering-plugin/pull/238))
+- **ce:review serial mode** — Pass `--serial` flag (or auto-detects when 6+ agents configured) to run review agents sequentially, preventing context limit crashes ([#237](https://github.com/EveryInc/compound-engineering-plugin/pull/237))
+- **agent-browser inspection & debugging commands** — Added JS eval, console/errors, network, storage, device emulation, element debugging, recording/tracing, tabs, and advanced mouse commands to agent-browser skill ([#236](https://github.com/EveryInc/compound-engineering-plugin/pull/236))
+- **test-browser port detection** — Auto-detects dev server port from CLAUDE.md, package.json, or .env files; supports `--port` flag ([#233](https://github.com/EveryInc/compound-engineering-plugin/pull/233))
+- **lfg phase gating** — Added explicit GATE checks between /lfg steps to enforce plan-before-work ordering ([#231](https://github.com/EveryInc/compound-engineering-plugin/pull/231))
+
+### Fixed
+
+- **Context7 API key auth** — MCP server config now passes `CONTEXT7_API_KEY` via `x-api-key` header to avoid anonymous rate limits ([#232](https://github.com/EveryInc/compound-engineering-plugin/pull/232))
+- **CLI: MCP server merge order** — `sync` now correctly overwrites same-named MCP servers with plugin values instead of preserving stale entries
+
+### Removed
+
+- **every-style-editor agent** — Removed duplicate agent; functionality already exists as `every-style-editor` skill ([#234](https://github.com/EveryInc/compound-engineering-plugin/pull/234))
