test(dlp): table-drive token-pattern detector cases

The token-pattern detector had 15 near-identical test methods across
`TestScanTokenPatterns` and `TestScanTokenPatternsExtended`, each
scanning a body carrying one synthetic token and asserting the reason
names the credential type.

Collapse them into a single `_TOKEN_PATTERN_CASES` table driven by
`subTest`, so adding a new token shape is a one-line row. Each case now
also asserts block severity (previously only the AWS case did).
`TestScanTokenPatternsExtended` is removed; its rows live in the table.
The non-matrix cases (clean text, location, context, reason) stay as
explicit methods. No production code change.

Closes #289

-# ADR 0004: Risk-weighted coverage, not a single global target
-
-- **Status:** Accepted
-- **Date:** 2026-06-25
-- **Deciders:** didericis
-
-## Context
-
-bot-bottle is a security tool: it sandboxes agents, scans egress for
-secret exfiltration, strips credentials, and gates git pushes. A latent
-bug in that logic is expensive, so test coverage there genuinely
-matters. But the repo also contains code where coverage is a poor
-signal:
-
-- **Interactive entry-point shells** — `cli/init.py` (a `read_tty_line()`
-  prompt loop) and `cli/tui.py` (a curses picker). Their bodies are I/O;
-  a unit test has to fake the entire terminal conversation, so it
-  inflates the number without asserting behaviour that would otherwise
-  go unchecked.
-- **Subprocess / backend orchestration** — the docker / smolmachines /
-  macos-container backends shell out to `docker`, `container`, `smolvm`.
-  Mock-heavy unit tests here mostly re-assert the argv you already
-  wrote (the test passes whether or not the real teardown works), while
-  many of the missed *branches* are failure paths you cannot provoke
-  against a real daemon on cue.
-
-Chasing a single global percentage (e.g. 90%) pushes the most test
-effort onto the least safety-relevant code — exactly backwards — and
-invites performative tests written to colour a line rather than to catch
-a regression (Goodhart's law).
-
-## Decision
-
-Coverage is **risk-weighted**, measured over the **combined unit +
-integration** suites, with three rules:
-
-1. **Critical modules target ≥ 90%.** The security/logic core —
-   `egress_addon{,_core}.py`, `dlp_detectors.py`, `egress.py`,
-   `manifest*.py`, `git_gate.py`, `git_http_backend.py`, `supervise.py`,
-   `yaml_subset.py`, `bottle_state.py` — is Docker-independent and
-   unit-testable, so it carries the high bar. We ratchet toward 90% as
-   these modules are touched; new gaps in them are not acceptable.
-
-2. **Subprocess/backend orchestration is covered by the integration
-   suite, not omitted.** `scripts/coverage.sh` runs unit + integration
-   under one coverage measurement so these modules are scored where they
-   are actually exercised. They stay *visible* — hiding the code that
-   tears down sandboxes and wires networks is the one place we will not
-   omit.
-
-3. **Interactive entry-point shells are omitted** (`.coveragerc`), with a
-   rationale comment. This is the only sanctioned use of `omit` besides
-   `tests/*`.
-
-The forward-looking guard is a **diff-coverage gate**
-(`scripts/diff_coverage.py`): new/changed executable lines on a branch
-must be ≥ 90% covered. This catches regressions where they are
-introduced without forcing a back-fill crusade through legacy glue. The
-gate skips lines in omitted files (there is no coverage data for them),
-so the omit list cannot launder *new* logic into the dark: anything that
-needs real testing must live outside the interactive shells to be
-scored at all.
-
-The **global percentage is informational**, not a CI gate — it would
-otherwise be hostage to the CI runner's Docker availability and to the
-omit list.
-
-## Consequences
-
-- The number we report (`scripts/coverage.sh`) means "coverage of the
-  code we consider testable, across both suites" — a dip is a real
-  regression in code we control, not noise from added CLI glue.
-- No incentive to write mock-the-mock tests for orchestration to defend
-  a global figure.
-- The omit list needs governance: an entry must be a genuinely
-  interactive shell, justified in the `.coveragerc` comment and here.
-  `cli/init.py` and `cli/tui.py` qualify; backend orchestration does
-  not.
-- CI must run the integration suite under coverage to score the
-  orchestration modules; where the runner lacks Docker those tests skip
-  and their modules read low — accepted, because the *enforced* gates
-  (critical-module standard + diff coverage) are Docker-independent.
-- "We're at N%" is now a curated figure; outsiders should read the
-  policy, not just the badge.
-
-## Links
-
-- PRs #290 (cover the egress adapter), and the coverage-policy PR that
-  introduces this record.
-- `.coveragerc`, `scripts/coverage.sh`, `scripts/diff_coverage.py`.
-- `scripts/critical-modules.txt` — the single source of truth for the
-  core-module list; read by both `scripts/coverage.sh` and the
-  `update-badges.yml` "core coverage" badge so they cannot drift.
-- The README carries a `core coverage` badge (auto-updated from that
-  list) — the headline number, distinct from the informational global
-  `coverage` badge.

-"""Unit: EgressAddon request/response decision flow (issue #286).
-
-`egress_addon.py` is the sidecar-only mitmproxy adapter that wires the
-host-importable decision logic in `egress_addon_core` into mitmproxy's
-request/response hooks. The core logic is exercised directly by
-`test_egress_addon_core.py`; the redaction logging by
-`test_egress_addon_log_redaction.py`. This file covers the adapter glue
-itself — `request()`, `response()`, `websocket_message()`, introspection,
-auth injection, git push/fetch blocking and the outbound-DLP policy
-branches — so `bot_bottle/egress_addon.py` no longer has to be omitted
-from coverage.
-
-mitmproxy is not installed on the host, so we pre-populate `sys.modules`
-with the minimum stubs needed to import the adapter (a `mitmproxy.http`
-module exposing a `Response` with `.make`, plus the flat
-`egress_addon_core` name the sidecar uses)."""
