fix(python-sdk): port current JS stripAnsi regex to strip_ansi_escape_codes

[mishushakov]

Summary

The Python SDK's strip_ansi_escape_codes (used to clean template build log messages) still used the old ansi-regex pattern, while the JS SDK's stripAnsi was rewritten in #895. This ports the current JS regex to Python so both SDKs clean logs identically: OSC sequences (hyperlinks, window titles) are matched non-greedily up to the first string terminator — including content spanning newlines — and CSI sequences are stripped without requiring a terminator.

Following review feedback, both implementations now also strip the remaining ECMA-48 string controls — DCS (Sixel, tmux passthrough), SOS, PM, and APC — through their string terminator, so control payloads don't leak into cleaned logs. This goes beyond upstream chalk/ansi-regex, click, and Rich, none of which fully strip DCS payloads, and restores what the old Python pattern handled.

Also mirrors the Python test suite into the JS SDK (which previously had no stripAnsi tests) — 20 identical cases per side — and verified byte-for-byte identical output between the two implementations on all of them. Includes a patch changeset for e2b and @e2b/python-sdk.

Example

Log messages that previously leaked OSC or DCS sequences into template build output are now cleaned:

from e2b.template.utils import strip_ansi_escape_codes

strip_ansi_escape_codes("\x1b]8;;https://e2b.dev\x07E2B\x1b]8;;\x07")  # "E2B"
strip_ansi_escape_codes("\x1b]0;title\nstill title\x07done")           # "done"
strip_ansi_escape_codes("\x1b[38:2::255:0:0mRED\x1b[0m")               # "RED"
strip_ansi_escape_codes("\x1bPq#0;2;0;0;0~~@@\x1b\\image")             # "image" (Sixel DCS)

PR Summary

Low Risk
Localized log-sanitization changes with broad mirrored tests; no auth, data, or API surface changes beyond cleaner template build messages.

Overview
Aligns template build log cleaning so the Python SDK’s strip_ansi_escape_codes matches the JS SDK’s stripAnsi regex, and both SDKs strip the same ECMA-48 control sequences.

Both implementations now treat OSC, DCS, SOS, PM, and APC as string controls: non-greedy match from ESC through the first string terminator (BEL, ESC\, or ST), including payloads that span newlines. CSI/SGR handling stays aligned (including colon-style params) without requiring a CSI terminator. Python compiles with re.ASCII so \d behavior matches JavaScript on CSI params.

Adds a mirrored Vitest suite for stripAnsi (JS had none) and expands the Python tests with the same cases (hyperlinks, Sixel DCS, unterminated DCS intro, non-ASCII digits). Patch changeset for e2b and @e2b/python-sdk.
