client/visitor: deduplicate visitor connection handshake and wrapping

Extract two shared helpers to eliminate duplicated code across STCP,
SUDP, and XTCP visitors:

- dialRawVisitorConn: handles ConnectServer + NewVisitorConn handshake
  (auth, sign key, 10s read deadline, error check)
- wrapVisitorConn: handles encryption + pooled compression wrapping,
  returning a recycleFn for pool resource cleanup

SUDP is upgraded from WithCompression to WithCompressionFromPool,
aligning with the pooled compression used by STCP and XTCP.

+`start` is a global allowlist evaluated after all sources are merged (config file/include/store).
+If `start` is non-empty, any proxy or visitor not listed there will not be started, including
+entries created via Store API.
+
+`start` is kept mainly for compatibility and is generally not recommended for new configurations.
+Prefer per-proxy/per-visitor `enabled`, and keep `start` empty unless you explicitly want this
+global allowlist behavior.

 You can run command `frpc verify -c ./frpc.toml` before reloading to check if there are config errors.

 ## 为什么使用 frp ？

Release.md

@@ -1,8 +1,9 @@
 ## Features
 
-* frpc now supports a `clientID` option to uniquely identify client instances. The server dashboard displays all connected clients with their online/offline status, connection history, and metadata, making it easier to monitor and manage multiple frpc deployments.
-* Redesigned the frp web dashboard with a modern UI, dark mode support, and improved navigation.
+* Added a built-in `store` capability for frpc, including persisted store source (`[store] path = "..."`), Store CRUD admin APIs (`/api/store/proxies*`, `/api/store/visitors*`) with runtime reload, and Store management pages in the frpc web dashboard.
 
-## Fixes
+## Improvements
 
-* Fixed UDP proxy protocol sending header on every packet instead of only the first packet of each session.
+* Kept proxy/visitor names as raw config names during completion; moved user-prefix handling to explicit wire-level naming logic.
+* Added `noweb` build tag to allow compiling without frontend assets. `make build` now auto-detects missing `web/*/dist` directories and skips embedding, so a fresh clone can build without running `make web` first. The dashboard gracefully returns 404 when assets are not embedded.
+* Improved config parsing errors: for `.toml` files, syntax errors now return immediately with parser position details (line/column when available) instead of falling through to YAML/JSON parsing, and TOML type mismatches report field-level errors without misleading line numbers.
