Verify future generated date against PR creation time.

Line 31 says Generated on : 2026-04-05, but this PR was created on April 4, 2026. Please confirm this is expected (timezone/automation behavior) to avoid timeline confusion in the catalog.

In `@README.md` at line 31, The README contains a generated date string "Generated
on : 2026-04-05" that does not match the PR creation date (Apr 4, 2026); update
the generation process to use the PR creation timestamp (or consistently use
UTC) and timezone-aware formatting so the generated date matches the PR creation
time, then regenerate the README to replace the "Generated on : YYYY-MM-DD" line
with the corrected date; locate the generator that emits the "Generated on :"
line and modify it to pull the PR creation time from the CI/PR metadata or
convert times to a single canonical timezone before formatting.

The entries in this JSON appear to be ordered by dtStart ascending (e.g., 2026-04-04, 2026-04-05, 2026-04-06, 2026-04-07). The newly added Aigamo.MatchGenerator item has dtStart 2026-04-05 but is appended after the 2026-04-07 entry, which breaks that ordering and makes the file harder to maintain (and may affect any code that assumes sorted input). Consider inserting this record next to the other 2026-04-05 entries (e.g., near TaggedEnum) instead of appending at the end.

In `@v2/book/list.html` at line 20, The heading text in v2/book/list.html contains
a raw '>' character ("This is the list of 266 RSCG with examples =>") that
violates HTMLHint spec-char-escape; update that heading (the line containing
that exact string) to escape the greater-than sign (replace '>' with '&gt;') so
the markup is lint-clean while preserving the visible text.

nuget.txt is used as the package description in the generated docs, but it currently contains the placeholder text "Package Description". Consider replacing this with the actual NuGet package description so the example page and search index have meaningful content.

⚠️ Potential issue | 🟡 Minor

Replace placeholder NuGet text with real package summary.

Line 1 still contains placeholder content (Package Description), which will surface as low-quality docs/metadata for this example.

Suggested fix 
-Package Description
+<actual one-line description of Aigamo.MatchGenerator from NuGet/package docs>
🤖 Prompt for AI Agents 
Verify each finding against the current code and only fix it if needed.

In `@v2/rscg_examples/Aigamo.MatchGenerator/nuget.txt` at line 1, Replace the
placeholder first line "Package Description" in nuget.txt with a concise real
NuGet package summary: a one-line sentence describing what Aigamo.MatchGenerator
does (its primary purpose), the target platform/framework (e.g., .NET version),
and the main capabilities or audience (e.g., match generation for
games/simulations), keeping it factual and under ~120 characters; update the
first line only so package metadata shows a meaningful summary rather than
placeholder text.
