Add src/daw/lua/common/crypto.lua with file and string hashing via sha256sum.

Functions

-- Returns "sha256:<hex>", nil | nil, err_string
M.hash_file(path)
M.hash_string(s)

Implementation notes

Both via io.popen() + sha256sum (POSIX, no external deps)
hash_string: uses echo -n to avoid trailing newline
Output format: "sha256:" .. hex (consistent with transaction_context hashes{})
Follows pattern of time.lua, yaml.lua

Deliverables

src/daw/lua/common/crypto.lua
test/test_crypto.lua
Makefile + README updated

Implementation: add get_raw() to http_client.lua

Needed by DAW/steurjan#16 (invoiceninja PDF download).
Without get_raw(), http_client always runs json.decode() on the response --
binary data (PDFs) comes back as a table instead of raw bytes.

Change: add M.get_raw(url, headers) -- same pattern as M.get() but skips
json.decode, returns raw string directly.

Consumers update accordingly:

src/adapters/invoice/invoiceninja/http.lua: get_raw() delegates to http_client.get_raw()
socket.http + ltn12 imports removed from http.lua (back to common-only)
