fix: address review feedback on coding-agent detection and AGENTS.md

Reuse the canonical marker sets (Cursor bugbot: duplicated detection,
Cursor masking, Aider false positives):
- detect_coding_agent() reimplemented Claude Code / Codex / Cursor detection
  with a narrower marker set than the existing CC_ENV_VAR, CODEX_ENV_VARS and
  CURSOR_ENV_VARS, and checked Cursor before Codex. A session exposing only
  CODEX_THREAD_ID was Codex to get_env_context() but unknown to telemetry,
  and Codex or Gemini running inside Cursor was reported as cursor because
  Cursor sets CURSOR_* in every integrated terminal.
- Add CODING_AGENT_ENV_MARKERS to crewai.utilities.constants as the single
  ordered source of truth, built from the three existing sets and matching
  get_env_context() precedence exactly. Verified the two signals now agree on
  all eight marker combinations, including Codex-inside-Cursor.
- Drop AIDER_MODEL: it is persistent user config, and crewai loads dotenv on
  normal runs, so a committed value would mislabel human executions. Drop
  AMP_AGENT (unverified, and the name collides with CrewAI AMP) and
  GITHUB_COPILOT_CLI (ambiguous). Documented that markers must be
  session-scoped, not configuration.
- Document that a result names the environment a process runs under, not
  proof an agent authored the code.

Preserve coding_agent under an external provider (CodeRabbit, major):
- The processor was only added to self.provider. set_tracer() leaves an
  application's pre-installed provider in place, and telemetry methods
  resolve their tracer globally, so every span in an instrumented app lost
  coding_agent entirely.
- Extract _attach_common_attributes() and call it for the existing provider
  too. Tracked in a WeakSet per provider, so both providers get the
  processor, neither gets it twice, and app providers are not kept alive.

Test isolation (CodeRabbit, major; Copilot):
- Add an isolated_telemetry fixture that replaces Telemetry._instance and
  suppresses shutdown-handler registration, instead of re-running __init__ on
  the shared singleton and stacking atexit/signal handlers.
- test_flow_creation_span_records_crewai_version now stubs coding_agent_span
  rather than mutating a private flag.
- Marker cases are derived from the shared table, so adding an assistant
  cannot leave tests checking a stale set. New tests cover precedence,
  agreement with get_env_context(), external-provider coverage, attach
  idempotency, and the no-config-markers rule.

AGENTS.md corrections:
- Qualify that a trace link is produced once tracing is enabled, rather than
  implying traces are always on (Copilot, CodeRabbit).
- First AMP deploy takes about a minute, not 10-15 minutes. Corrected in both
  the new section and the pre-existing text that carried the same claim
  (CodeRabbit).
- Warn that anyone holding a trace link can read the trace, which may include
  task inputs and outputs, tool arguments and results, and LLM prompts and
  responses; point at redaction and retention settings (CodeRabbit, major).
- Add a table separating traces from anonymous telemetry and their
  independent controls. CodeRabbit asked for the opposite claim - that
  CREWAI_TRACING_ENABLED does not imply export when OTEL_SDK_DISABLED or
  CREWAI_DISABLE_TELEMETRY are set - but is_tracing_enabled() reads only the
  tracing settings, so the two systems are genuinely independent and that
  wording would have been wrong.

Vulnerability scan (pre-existing on main, not introduced here):
- nltk 3.9.4 is affected by GHSA-qvv7-cg9c-w4x3, GHSA-fg7f-2386-8897 and
  GHSA-xh95-f55m-82fw, all fixed in 3.10.0. Add an nltk>=3.10.0 floor.
- 3.10.0 also clears PYSEC-2026-597, whose last affected version is 3.9.4, so
  remove that now-stale --ignore-vuln entry.
- pip-audit against the updated lock reports no known vulnerabilities.

Lint: ruff format (CI runs --check; only ruff check had been run locally).
