`asm` now lexes as a dedicated `kw_asm` keyword (Token.Tag + keyword map entry).
`volatile` and `clobbers` stay out of the global keyword table — they are
recognized contextually only inside an `asm { … }` body (PLAN-ASM Deviation 4).
- token.zig: kw_asm tag + `.{ "asm", .kw_asm }` map entry.
- lsp/server.zig: classifyToken exhaustive switch gained the .kw_asm arm
(the new enum value forced coverage — intended tripwire).
- lexer.test.zig (new, wired into root.zig barrel): locks `asm`->kw_asm and
`volatile`/`clobbers`->identifier.
Lock commit (behavior-locking passing test). zig build test green (445 unit).
