rpc: comments are instant and newlines no longer vanish

Two fixes to the comment verb:

Drop the per-character typing delay. Rename/retype/goto use a 35 ms delay for
the visual effect (the agent's keystrokes appear one by one on the livestream),
but comments can be long — a 200-char annotation blocked the driver for 7 s of
pure animation. Comments now type instantly (delay=0); the aesthetic delay is
kept for rename, retype and goto where values are short.

Escape literal newlines before injecting into the prompt. The Input widget is
single-line, so a real 0x0a sent as a keystroke was silently swallowed. The
app's _do_comment already converts the two-char sequence '\\n' into a real
newline for IDA, so the RPC layer now does text.replace('\\n', '\\\\n')
before typing — both literal newlines from the caller and explicit \\n in the
text reach IDA as multi-line comments (each line gets its own // prefix in the
decompiler).

Verified on a live pane: a comment with an embedded newline now renders as two
// lines in the pseudocode, and long comments appear without the multi-second
typing pause.
