fix(observability): enrich server log on CommitMemory plugin error

The POST /workspaces/:id/memories handler returns a generic
HTTP 500 'failed to store memory' when the underlying v2
memory plugin's CommitMemory call errors. The current
log.Printf('Commit memory error (plugin): %v', err) emits
only the error — operators have no workspace, scope, or
namespace context to diagnose recurring main incidents
(continuous-synth E2E + HMA memory-commit both currently
fail with this 500; the backend error is swallowed).

Fix: enrich the server-side log line with workspaceID, the
requested scope, the resolved v2 namespace, a structured
err_class=<type> field (for log-aggregator filtering),
and the quoted err text (preserves trailing whitespace /
special chars that %v would munge).

Hard constraint (same discipline as the #2392 leak fix):
the underlying err stays server-log-only. The HTTP
response body is UNCHANGED — still 500 'failed to store
memory' with no plugin error leaked to the client.

No behavior change to the write path itself. The change
is one log.Printf line + a 9-line comment explaining the
no-leak discipline. The new log line is:

  log.Printf('Commit memory plugin error: workspace=%s scope=%s namespace=%s err_class=%T err=%q',
      workspaceID, body.Scope, nsName, err, err)

Unblocks operator diagnosis of the memory-v2 backend
without changing the client surface or weakening the
server's error-disclosure posture.

-# sop-tier-check — verify a Gitea PR satisfies the §SOP-6 approval gate.
-#
-# Reads the PR's tier label, walks approving reviewers, and checks team
-# membership against the tier's approval expression. Passes only when
-# ALL clauses in the expression are satisfied by the set of approving
-# reviewers (AND-composition; internal#189).
-#
-# Expression syntax:
-#   "team-a"          — OR-set: any ONE of the comma-separated teams
-#   "team-a AND team-b" — AND: BOTH must each have ≥1 approver
-#   "(a,b,c)"         — OR-set wrapped in parens; same as "a,b,c"
-#
-# Example: "qa AND security AND (managers,ceo)" means:
-#   ≥1 approver in team "qa"  AND
-#   ≥1 approver in team "security"  AND
-#   ≥1 approver in team "managers" OR "ceo"
-#
-# Per the spec (internal#189), the hard gate here pairs with the
-# advisory gate of sop-conformance LLM-judge (internal#188): each
-# required-team click must reflect real verification (visible in review
-# body or A2A messages), not rubber-stamp APPROVE. Both gates together
-# close the "teammate clicks APPROVE without verifying" gap.
-#
-# Invoked from `.gitea/workflows/sop-tier-check.yml`. The workflow sets
-# the env vars below; this script does no IO outside of stdout/stderr +
-# the Gitea API.
-#
-# Required env:
-#   GITEA_TOKEN   — bot PAT with read:organization,read:user,
-#                   read:issue,read:repository scopes
-#   GITEA_HOST    — e.g. git.moleculesai.app

-#   PR_NUMBER     — int (from github.event.pull_request.number)
-#   PR_AUTHOR     — login (from github.event.pull_request.user.login)

-# Optional:
-#   SOP_DEBUG=1        — print per-API-call diagnostic lines. Default: off.

-# Security regression test for the SOP tier-gate AUTHORIZATION bypass.
-#
-# Bug (fixed in fix/sop-tier-authz-no-org-fallback):
-#   sop-tier-check.sh probed team membership at /teams/{id}/members/{user}.
-#   If EVERY team probe failed (e.g. 403 — token lacks read:organization, or
-#   any visibility/flakiness gap), it FELL BACK to /orgs/{org}/members/{user}
-#   and credited that org member as a member of EVERY queried team. The
-#   evaluator then treated those synthetic memberships as real, so a plain
-#   NON-CEO org member satisfied tier:high (ceo). A visibility/auth gap became
-#   a real highest-tier authorization PASS — privilege escalation.
-#
-# Fix (fail-closed authorization):
-#   - The org-member ⇒ "member of all teams" fallback is REMOVED. Org
-#     membership is never credited as team membership.
-#   - A team probe that returns anything other than 200/204 (member) or 404
-#     (verified non-member) is a CANNOT-VERIFY condition: the gate fails loud
-#     (exit 1) with a cannot-verify status and never grants the tier.
-#
-# Method: this is a true end-to-end test. It prepends a fake `curl` to PATH
-# that serves canned Gitea API responses keyed by URL, then runs the REAL
-# sop-tier-check.sh. The fake exercises the genuine probe→credit→evaluate
-# path — no logic is re-implemented in the test.

-#
-# Closes internal#292. Gitea 1.22.6 doesn't refire workflows on the
-# `pull_request_review` event (go-gitea/gitea#33700); the `sop-tier-check`
-# workflow's review-event subscription is silently dead. The result:
-# PRs that get their approving review AFTER the tier-check ran on open/
-# synchronize keep their failing status check forever, and the only way
-# to merge is the admin force-merge path (audited via `audit-force-merge`
-# but the audit trail keeps growing; see `feedback_never_admin_merge_bypass`).
-#
-# Comment-triggered refires now live in `review-refire-comments.yml`. Gitea
-# queues issue_comment workflows before evaluating job-level `if:`, so having
-# qa-review, security-review, sop-checklist, and sop-tier-refire all subscribe
-# to every comment caused queue storms on SOP-heavy PRs. This workflow is a
-# non-automatic breadcrumb only; Gitea 1.22.6 does not support
-# workflow_dispatch inputs, so real refires must use `/refire-tier-check`.
-#
-# SECURITY MODEL:
-#
-# 1. `pull_request` exists on the issue (issue_comment fires on issues
-#    AND PRs; we only want PRs).
-# 2. `comment.author_association` must be MEMBER/OWNER/COLLABORATOR.
-#    Per the internal#292 core-security review (review#1066 ask): anyone
-#    can comment, but only repo collaborators+ can flip the status.
-#    Without this gate, a drive-by commenter on a public-issue-tracker
-#    surface could trigger a status flip.
-# 3. Comment body must contain `/refire-tier-check` — a slash-command-
-#    shaped trigger (not just any comment word). Prevents accidental
-#    triggering from prose like "we should refire tests" in a review.
-# 4. This workflow does NOT check out PR HEAD code. Like sop-tier-check,
-#    it only HTTP-calls the Gitea API. Trust boundary preserved.
-#
-# Note: `issue_comment` fires from the BASE branch's workflow file. There
-# is no `pull_request_target` equivalent to set; the trigger inherently
-# loads the workflow from the default branch.
