Remove the transport-shaping tuning footguns that could break data flow if
misconfigured, and hardcode them to xray-core / Go net/http2 defaults instead:
- HTTP/2: stop overriding MaxConcurrentStreams and the per-conn/per-stream upload
buffers; use Go's defaults exactly like xray-core's splithttp hub does.
- XHTTP reorder buffer default is now 30 (xray-core scMaxBufferedPosts), still
overridable per-inbound from the generated config.
- Mux per-connection session cap, mux UDP idle/read/write buffers, and the XHTTP
session cap are now fixed constants rather than admin knobs.
The XrayNativeTuning struct and admin UI keep only the operator-safe controls:
Go GOMAXPROCS, the global mux-session DoS cap, and the packet-trace debug toggle.
Old config.json files with the removed keys still load (unknown fields ignored).

Fix the two reliability problems in the in-process Xray emulator by matching
XTLS/Xray-core's transport semantics:
- XHTTP upload queue: rewrite as a faithful port of xray-core's uploadQueue
(bounded channel + sequence reorder heap). Packet-up POSTs are now acked
immediately on buffering instead of blocking until the tunnel reader consumes
them. The old block-until-consumed behavior throttled the uplink to the
reassembly rate and deadlocked against the client's concurrent-POST limit,
which showed up as "download a burst, stall, repeat" on video/large downloads.
- Mux: dial the backend and pump uplink on a per-session goroutine fed by a
bounded channel (mirrors xray-core's per-session buffered pipe). Previously the
dial and backend writes ran inline in the shared read loop, so one slow target
or backpressured session stalled every other muxed session.
- XHTTP download writer: flush every write (matches httpServerConn.Write) instead
of batching behind a 2ms/32KB window.
- XHTTP: enforce a single download (stream-down) per session to stop two GETs
from splitting the decoded stream and corrupting the tunnel.
- Fix a close-of-closed-channel race in the mux session teardown (sync.Once).
Remove the now-inert XHTTP tuning knobs (xhttp_queue_timeout_ms, xhttp_flush_ms,
xhttp_flush_bytes) from the backend struct and the admin panel UI.
Split admin/assets/app.js into ordered classic-script modules under
admin/assets/js/ for maintainability. The concatenation is byte-identical to the
old file and load order is preserved via defer, so behavior is unchanged.
Add regression tests for the mux head-of-line stall and the out-of-order
packet-up burst-stall; add golang.org/x/text to go.mod so tests build.
