Good First Issue: Add Go language detection + symbol regex to peek find

[hariomlohardev]

Description

Split from #36 — tree-sitter for JS/TS/Go/Rust/Java is too big for one PR. This is the Go slice: ~1 file, 30 min.

Files

• peek/peek/symbols.py — add GO_FUNC_RE and handle f.language == "go"
• peek/tests/test_symbols.py — add test_symbols_go

Acceptance

• index_symbols on a a.go with func Foo() returns Symbol(name="Foo")
• pytest -q passes

Time

~30 min — great for first PR after you’ve done one JS/TS one!

Good first issue — per-language split of #36
