fix: reduce vuepress build memory footprint with heap limit and vite config

- Set `NODE_OPTIONS='--max-old-space-size=768'` in package.json build script to cap V8 heap and prevent OOM
- Disabled sourcemaps and compressed size reporting in Vite config to lower memory usage during build
- Updated sitemap lastmod dates to reflect recent changes
- Added task documentation for memory profiling and optimization results in prompts directory

+## Context
+
+@Clanker Read the `AGENTS.md` and `README.md` to get an understanding of the project.
+
+## Task
+
+I run `task build-vuepress` it will first execute some pre-build actions and then use `vuepress` with `viteBundler` to create a static site. The later action uses a lot of memory. Create a memory profile and then propose ways to reduce the memory footprint.
+
+Maybe there are NODE options to limit the memory. Or maybe a different bundler can be used. 
+
+## Worklog
+
+### Memory Profile Results
+
+The VuePress build was profiled by monitoring `/proc/<pid>/status` (VmPeak/VmHWM) during a full `npm run build`.
+
+**Baseline (no optimizations):**
+- Peak Virtual Memory (VmPeak): ~22,500 MB
+- Peak Resident Memory (VmHWM): ~2,440 MB
+- Build time: ~30 s
+- Pages rendered: 911
+
+**Memory use by phase:**
+1. Init/prepare: ~350-420 MB resident
+2. Vite compile: spikes to ~1,800-2,000 MB resident
+3. SSR render (911 pages): peaks at ~2,440 MB resident
+
+**Key observations:**
+- The `vite:vue` plugin consumes 30-67% of compile time.
+- The `vuepress:markdown` plugin consumes 10-47%.
+- The `vite:asset` plugin consumes 16-22%.
+- `build.js` copies 1,549 attachment files (images, GIFs, videos) into `src/`, where Vite processes them as assets.
+
+### Implemented Optimizations
+
+**1. Vite build tuning (`src/.vuepress/config.js`)**
+- Added `sourcemap: false` to the Vite `build` options.
+- Added `reportCompressedSize: false` to the Vite `build` options.
+- This avoids memory/time spent generating source maps and calculating gzip/brotli sizes for all assets.
+
+**2. Node.js heap limit (`package.json`)**
+- Set `NODE_OPTIONS='--max-old-space-size=768'` on the `build` script.
+- This caps the V8 old-generation heap, forcing more frequent garbage collection and preventing unbounded heap growth.
+- Heap-limit stress tests showed the build still succeeds down to `--max-old-space-size=512`; it OOMs at `384`.
+
+**Optimized result:**
+- Peak Resident Memory: ~2,000-2,050 MB (~15-18% reduction vs baseline)
+- Build time: ~28-30 s (negligible change)
+- Build completes successfully
+
+### Other Options Considered
+
+**Move attachments to `public/` folder (`src/.vuepress/public/attachments/`)**
+- This prevents Vite from processing the 1,549 image/GIF files through its asset pipeline.
+- Tested: reduced peak resident memory further to ~1,800 MB (~26% reduction).
+- Trade-off: compile phase increased from ~5 s to ~25 s, total build time from ~28 s to ~46 s.
+- **Not implemented** because the memory savings do not justify the significant build-time regression.
+
+**Switch bundler (`@vuepress/bundler-webpack`)**
+- Not installed. Webpack generally uses *more* memory than Vite for large docs sites, so this was not pursued.
+
+**Disable `slimsearchPlugin.indexContent`**
+- Temporarily setting `indexContent: false` saved ~80 MB.
+- **Not implemented** because full-text search is a core feature.
+
+### Files Changed
+
+- `src/.vuepress/config.js` – added `viteOptions.build.sourcemap: false` and `reportCompressedSize: false`
+- `package.json` – added `NODE_OPTIONS='--max-old-space-size=768'` to the `build` script
+
+### Recommendations
+
+1. Keep the two implemented changes (Vite options + Node heap limit). They provide a ~15-18% memory reduction with no functional loss and minimal build-time impact.
+2. If memory needs to be reduced further in the future, consider moving attachments to the `public/` folder, accepting the ~60% build-time increase.
+3. Monitor build times and memory on CI runners with these settings.
