Implement the 4 empty function bodies in specs/tri/utils/args.t27

[gHashTag]

Context

specs/tri/utils/args.t27 declares module TriArgs in 77 lines. 4 of its functions are declared with a body that holds no statement — a signature and a comment where the implementation belongs.

.t27 is the hand-authored source language. t27c compiles it out to C, Rust, Verilog and Zig. You are writing source, not compiler output, and not prose about an implementation.

Current state — re-run these yourself

$ cd /Users/playom/t27
$ /Users/playom/t27/target/release/t27c gen specs/tri/utils/args.t27 2>&1 | grep -c 'not yet implemented'
4
$ /Users/playom/t27/target/release/t27c parse specs/tri/utils/args.t27 2>&1 | grep -E '^(recovery-events|declarations-swallowed|lexer-discarded-chars):'
recovery-events: 0
declarations-swallowed: 0
lexer-discarded-chars: 0

Use ./target/release/t27c, not the t27c on PATH: the PATH build prints no parse metrics at all, so the grep above returns nothing and an empty result reads as a pass.

What to write

Keep every signature exactly as it is — the signature is the contract. Quoted verbatim from the file:

1. line 35 — fn parse(allocator: std.mem.Allocator) -> void
2. line 40 — fn has_flag(result: ParseResult) -> void
3. line 45 — fn get_value(result: ParseResult) -> void
4. line 50 — fn get_positional(result: ParseResult) -> void

The file already has 0 test block(s). Add one for each function you implement; a body with nothing asserting on it is a claim, not a result.

Acceptance criteria

• 1. /Users/playom/t27/target/release/t27c gen specs/tri/utils/args.t27 2>&1 | grep -c 'not yet implemented' prints 0
• 2. with criterion 1 satisfied, /Users/playom/t27/target/release/t27c parse specs/tri/utils/args.t27 2>&1 | grep -E '^(recovery-events|declarations-swallowed|lexer-discarded-chars):' reports 0, 0 and 0
• 3. with criterion 1 satisfied, all 4 names above still exist: grep -cE '^\s*(pub )?fn (parse|has_flag|get_value|get_positional)\(' specs/tri/utils/args.t27 prints 4
• 4. grep -c '^\s*test "' specs/tri/utils/args.t27 prints at least 4 (today: 0)
