🍺 README: add Homebrew install as the recommended option

The Homebrew tap at study8677/homebrew-tap is now live with the
v0.3.0 formula. brew install handles dependency resolution (Go is
fetched automatically as a build dep), drops the binary in PATH, and
prints a caveats block with skill-install commands.

Demoted curl|bash to "alternative one-line installer" and noted the
Go version requirement so users know what to expect.

Also tightened the manual-install example: use ~/.local/bin first
(no sudo) and skip the cp -r in favor of an explicit mkdir + cp of
just the SKILL.md.

Verified locally: brew install study8677/tap/avc completes in ~9s
(plus Go bottle download on first install), brew test passes,
avc --version returns 0.3.0.

 ### Install
 
-**One-line install** (builds binary + installs skills for all detected agents):
+**🍺 Homebrew (macOS / Linuxbrew, recommended)**
+
+```bash
+brew install study8677/tap/avc
+```
+
+After install, `brew info avc` prints one-line copy commands to wire the skill into Claude Code / Codex / Gemini.
+
+**🚀 One-line installer** (builds from source + auto-installs skills for every detected agent)
 
 ```bash
 curl -sSL https://raw.githubusercontent.com/study8677/Agent_View_Controller-AVC/main/install.sh | bash
