fix: report per-file progress while downloading Mojang Java

MojangJavaDownloadTask never called updateProgress, so its progress bar stayed
indeterminate while the hidden LZMA-decompress and cache-copy steps wrote files
to disk. Players saw 0KB speed and a frozen-looking bar and restarted the
launcher. Append a progress callback after each file completes so the bar
advances through download/decompress/copy phases; the download logic is unchanged.

+# TDLMPack consume path for TDLM/HMCL
+
+TDLMPack does **not** pull this launcher via Maven, a version pin, or a pack-build download step.
+The pack build publishes the HMCL Server Modpack client (`server-manifest.json` + `overrides/`)
+under the `tdlm-client/latest` layout. Players install the launcher separately.
+
+## After this repo’s publish workflow
+
+Run **Actions → Publish TDLM launcher → Run workflow** with a new `release_tag`.
+
+### Secrets (sibling pattern)
+
+| Name | Where it lives today | Used by |
+|---|---|---|
+| `MAVEN_USER` / `MAVEN_PASSWORD` | **Org** secrets | Stratum / mod Maven publish — **not** used for launcher binaries |
+| `TDLM_PACK_TOKEN` | **TDLMPack repo** secret only (not org) | TDLMPack `pack.yml` Gitea package + release uploads |
+| `github.token` | Actions runtime | HMCL publish fallback when `TDLM_PACK_TOKEN` is unset |
+
+HMCL `publish-tdlm.yml` uses the **same name** as TDLMPack: `secrets.TDLM_PACK_TOKEN`, then falls back to `github.token`.
+Org Maven secrets cannot publish Gitea generic packages / releases.
+
+**Recommended:** promote `TDLM_PACK_TOKEN` to an **org** secret (like `MAVEN_*`) so HMCL inherits it with no new repo secret. Until then, either copy it onto `TDLM/HMCL` or rely on `github.token` (same-repo release usually works; org `tdlm-hmcl` package write may still need the pack token).
+
+### 1. Stable generic URLs (preferred for README / curl / CI)
+
+Overwrite-in-place, same host style as the client fileApi:
+
+```text
+https://git.nest.potatolab.uk:8443/api/packages/TDLM/generic/tdlm-hmcl/latest/HMCL.exe
+https://git.nest.potatolab.uk:8443/api/packages/TDLM/generic/tdlm-hmcl/latest/HMCL.jar
+```
+
+Checksums (when published): `HMCL.exe.sha256`, `HMCL.jar.sha256` next to those names.
+
+### 2. Gitea Release (versioned page)
+
+```text
+https://git.potatolab.uk/TDLM/HMCL/releases/latest
+```
+
+Assets on each tag: `HMCL.exe`, `HMCL.jar`, plus `.sha256` files.
+(Use the nest API host for scripted uploads; public download links on `git.potatolab.uk` are fine for browsers.)
+
+### 3. What TDLMPack should change
+
+In `TDLM/TDLMPack` README §启动, replace the repo-only “安装 TDLM/HMCL” step with one of the URLs above.
+**Do not** add HMCL as a Gradle/Maven dependency of the pack — pack CI stays pack-only.
+
+### 4. Client pack fileApi (self-hosted VPS)
+
+HMCL default (`Metadata.DEFAULT_CLIENT_FILE_API`):
+
+```text
+http://159.75.5.225:19527/tdlm-client
+```
+
+First install / updates fetch `{fileApi}/server-manifest.json` (and `overrides/**` under that root).
+Override at runtime: `-Dhmcl.client.fileApi=…` or jar attribute `hmcl.client.fileApi`.
+
+The fileApi is a read-only nginx static mirror on the TDLM VPS (`159.75.5.225`, port `19527`,
+root `/var/www/tdlm-dl`). Players read it anonymously; integrity is verified by the SHA-1 hashes
+in `server-manifest.json`.
+
+**TDLMPack must use the same URL** so `server-manifest.json` embeds it:
+
+```text
+TDLM_CLIENT_FILE_API=http://159.75.5.225:19527/tdlm-client
+```
+
+Set that as the Gitea Actions **variable** on `TDLM/TDLMPack` (pack.yml passes `vars.TDLM_CLIENT_FILE_API`;
+`PackBuild.DEFAULT_FILE_API` is the build-time fallback).
+
+**Publish path (upload origin split from public fileApi):** Pack CI no longer PUTs to the read URL.
+The `pack.yml` "Publish the client Server Modpack to fileApi" step rsyncs `build/pack/client/overrides/`
+then `server-manifest.json` (manifest last) over SSH to `ubuntu@159.75.5.225:/var/www/tdlm-dl/tdlm-client`.
+Auth is the repo secret `TDLM_VPS_SSH_KEY`, an ed25519 deploy key confined on the VPS by
+`command="/usr/bin/rrsync /var/www/tdlm-dl/tdlm-client"` (rsync-only, no shell, no forwarding).
+The public port 19527 serves GET/HEAD only — there is no public write surface.
