config: orient_task_aware off on all profiles + --orient/--no-orient CLI flag

[FMXExpress]

What

Makes task-aware MEMORY slicing (orient_task_aware, PasClaw.Agent.Orient) off by default on every profile, and adds a per-run CLI flag to toggle it:

pasclaw agent --orient    -m "…"   # force task-aware MEMORY slicing on for this run
pasclaw agent --no-orient -m "…"   # force whole-file injection (overrides config.json)

Why

#314 flipped OrientTaskAware to on-by-default in TConfig.Create and in the stock / low-token / all-on profiles — but left several places still describing it as off:

• docs/configuration.md table → false
• onboarding (PromptOrientTaskAware) → default N, comment "Cfg default off"
• loop_shaping_defaults_tests → asserted OrientTaskAware False

That inconsistency (only the code default + 3 profiles got flipped, nothing else) strongly suggests the on-flip was unintended. This PR reverts it and makes enabling it an explicit, per-invocation choice — whole-file injection is the long-standing contract, and slicing changes what the model sees, so it shouldn't be silently on.

Changes

Default & serialization (PasClaw.Config.pas)

• TConfig.Create: OrientTaskAware := False.
• SaveConfig: emit orient_task_aware only when on (emit-when-on, matching the off default) so fresh configs stay tidy and an opt-in round-trips.

Profiles (PasClaw.Config.Profile.pas)

• Drop orient_task_aware:true from stock, low-token, and all-on (and therefore max-build, which inherits low-token). No built-in profile enables it. Descriptions updated; stock stays in lockstep with TConfig.Create.

CLI (PasClaw.Cmd.Agent.pas)

• New TOrientOverride tri-state (ooUnset/ooOn/ooOff); --orient/--no-orient parse into it; applied right after LoadConfig(A.Profile) so the flag overrides whatever config/profile resolved to. Usage text updated. Forwarded automatically by pasclaw build (it passes through agent flags).

Tests

• config_profile_tests: assert no profile enables orient and the inherit chain keeps it off; the round-trip test now exercises orient as an opt-in (default-off) round-trip.
• loop_shaping_defaults_tests: was already red on main (config: adopt lean-edit shape for stock defaults + hashline opt-in onboarding #314 reverted vault/web_fetch to off without updating it) — brought fully in line with the actual current TConfig.Create defaults (vault/web off, orient off), so make test is green again.

Docs: configuration.md, memory.md, README.md note the --orient/--no-orient flag and that it's off on every profile.

Verification

• make all clean.
• make test-config-profile, make test-loop-shaping-defaults, make test-orient, make test-plan-build-mode all pass (loop-shaping went from red→green).
• Binary usage now lists [--orient|--no-orient].
