ginuerzh 1b07475bf3 feat(forwarder): support plugin-based rewriter in HTTP body rewrite rules
Each rewriteBody/rewriteResponseBody/rewriteRequestBody rule can now
optionally reference a named rewriter plugin (HTTP/gRPC backend) via
the rewriter field. When set, body rewriting delegates to the plugin
rather than applying pattern/replacement, while content-type filtering
still applies.

Coincident fixes:
- rewriter/plugin/grpc: return nil when conn is nil (avoid nil-ptr panic)
- rewriter/plugin/http: drain response body in defer to prevent leaks
- config/parsing/rewriter: pass TimeoutOption to gRPC plugin
- config/parsing/service: warn when referenced rewriter is not registered

ginuerzh cd97e5e746 fix(hop): skip priority short-circuit when multiple nodes share the same priority
When two or more nodes have an identical matcher rule they receive
identical default priority (rule string length). The priority shortcut
assumed the top-priority node was the single authoritative choice and
returned it directly, bypassing the selector (FailFilter, BackupFilter,
strategy) — so weight, round-robin, and hash were silently ignored.

Add a third condition: the top priority must be strictly greater than
the second-highest. When multiple nodes share the same highest priority
the selector applies normally for load balancing.

Add doc comments on NodeMatcherConfig.Priority explaining the three
semantic ranges (0=auto, negative=always-selector, positive=shortcut).

ginuerzh cf89192211 feat(forwarder/sniffer): add HTTP request body rewriting, deprecate rewriteBody in favor of rewriteResponseBody
- Add RewriteRequestBody field to HTTPNodeConfig (yaml: rewriteRequestBody)
- Add RewriteRequestBody field to HTTPNodeSettings in core chain
- Add rewriteReqBody function symmetric to rewriteRespBody in sniffer_rewrite.go
- Wire up rewriteReqBody call in httpRoundTrip before body wrapping for recording
- Add new RewriteResponseBody config field, deprecate old RewriteBody
- Parse both RewriteRequestBody and RewriteResponseBody in node config parsing
- Add 10 test cases covering nil, skip, content-type filter, and chained rewrites
- Bump core dependency to v0.4.1
- Fix: clone response header map in internal/util/sniffing/sniffer_http.go

ginuerzh effba3b690 docs(parsing): add package and symbol doc comments
Add godoc comments for all 62 exported symbols across 20 files in
config/parsing/: 23 MDKey constants, 35 Parse*/List/Default* functions,
3 TLS helpers, 1 Args struct with 7 fields, and the package doc.

ginuerzh 2b1e4ca3a7 test(parsing): add 229 unit tests across 18 config/parsing packages
Covering nil-input safety, plugin backends (HTTP/gRPC/default), loaders
(File/HTTP/Redis), selector strategies, edge cases (empty/invalid inputs),
and hop-to-node metadata inheritance. All tests passing.

ginuerzh 9febb23bc9 fix(config): stop mutating shared config structs during parsing
Prevent data loss and nil panics across 5 parse functions:
- chain: nil-guard hop entries to avoid deref on empty YAML lists
- hop: build merged metadata map instead of writing inherited values
  into the original NodeConfig; swap+restore around ParseNode call
- node: use local connCfg/dialCfg instead of overwriting cfg.Connector
  and cfg.Dialer fields; only fill in Type when empty
- parser: preserve existing config file fields when env vars override
  Level/Addr (was replacing the entire struct)
- router: only update ipNet from dst CIDR if parse succeeds, keeping
  the route.Net fallback instead of overwriting with nil

ginuerzh 238a0b95b7 feat: upgrade core to v0.4.0, pass network to admission, add dial options
Upgrade github.com/go-gost/core from v0.3.3 to v0.4.0, adapting to
interface changes:
- Admit(ctx, network, addr, opts) now accepts a network parameter
- Router.Dial now accepts variadic chain.DialOption, forwarded to
  the route's Dial call along with router-level options
- gRPC/HTTP admission plugins include the new Network field

Also fix two typos: ResoloverNodeOption -> ResolverNodeOption,
WithHostOpton -> WithHostOption.
