Remove trivial comment-only lines across asm, sec, stdlib and VM headers

[rafael84]

Motivation

• Remove noisy, trivial comment-only separator lines (lines containing only ; or // or repeating divider characters) to clean up source and documentation across assembler examples, stdlib includes, and VM headers.

Description

• Stripped standalone comment-only lines from tutorial assemblies in asm/ and sec/, from stdlib/asm/tiny16.inc, and from VM headers and the assembler entrypoint, touching 58 files with ~197 deletions.
• The change is purely cosmetic: only lines matching the trivial-comment pattern were removed and meaningful inline comments and documentation blocks were preserved.
• The cleanup was performed by a scripted sweep that removes lines matching ^\s*(//|;)\s*$ and similar divider lines.

Testing

• Executed the cleanup script which reported updated 58 files and produced the set of modified files as expected.
• Verified there are no remaining trivial comment-only lines by running rg against the affected directories, which returned no matches.
• Ran make format to apply formatting, but it failed because clang-format reported: "Configuration file(s) do(es) not support C++", so formatting did not complete successfully.
