Diego Rodrigues de Sa e Souza e117249baa cherry-pick(pr-9738): feat(logging): make the chat-log truncation limit configurable, bumped default 128x (#9863)
* feat(logging): make the chat-log truncation limit configurable, bumped default 128x

The 8KB cap on logged request/response bodies
(open-sse/handlers/chatCore/logTruncation.ts::truncateForLog()) was
hardcoded — trivially exceeded by any real multi-turn agentic
conversation, meaning the dashboard's "Full Conversation" panel could
only ever show a placeholder instead of the actual messages for nearly
every logged row of any conversation with real substance.

- Added CHAT_LOG_MAX_BODY_KB env var (src/lib/logEnv.ts::
  getChatLogMaxBodyBytes()), default 1024 KB (1MB) — a 128x bump from
  the old hardcoded 8KB — following the same configurable-limit pattern
  as the sibling CHAT_LOG_TEXT_LIMIT/CHAT_LOG_ARRAY_TAIL_ITEMS/etc. vars.
- Documented in .env.example and docs/reference/ENVIRONMENT.md.

estimateSizeFast() (open-sse/utils/estimateSize.ts) has been
substantially rewritten upstream since this bug was first found (now an
iterative Frame-based walker with a separate node-visit budget, not the
simple stack loop originally patched) — re-implemented the fix against
the current algorithm rather than porting the old diff: the byte
early-exit was unconditionally the module-level ESTIMATE_SIZE_BYTE_LIMIT
(256 KiB) with no way for a caller to raise it, so any caller comparing
against a bigger configured threshold could never see a size above
~256 KiB — every payload between 256 KiB and the caller's real limit
looked "under threshold" and truncation never fired, the opposite of
intended. Added an optional byteLimit parameter (default unchanged at
ESTIMATE_SIZE_BYTE_LIMIT, so isSmallEnoughForSemanticCache's existing
behavior is untouched) threaded through both the byte-check early-exit
and the node-budget-exhaustion fail-closed fallback, with
truncateForLog() now passing its own configured getChatLogMaxBodyBytes()
value through.

* feat(dashboard): show conversation session tag in request detail metadata

Adds a "Conversation" field to the request detail panel's metadata
grid (after "Combo"), showing the request's conversation id
(sessionTag) for quick reference/copy.
